• Build trust with visitors by showing the padlock icon in the browser’s address bar.

Without a valid SSL certificate, your website may appear unsafe, driving potential visitors away. SSLforWeb helps you secure your website with trusted SSL certificates. It makes the process of installing SSL simple and hassle-free. Using SSLforWeb, you can easily fix SSL issues that might arise after installation, protect sensitive data, build user trust, and improve your site’s search engine rankings effortlessly.

Common SSL Certificate Issues You May Face

Let’s identify the most common SSL issues and the best fixes for them. Each of these problems can cause errors like NET::ERR_CERT_COMMON_NAME_INVALID, SSL Handshake Failed, or Your connection is not private. By understanding these errors and learning how to fix SSL issues, you can troubleshoot problems quickly and ensure your website remains secure.

1. SSL Certificate Has Expired

One of the most frequent issues is an expired certificate. SSL certificates have validity periods (90 days, 1 year, or 2 years). When they expire, browsers instantly flag your site as unsafe.

Symptoms

• Visitors see “Your connection is not private.”
• Browsers show error codes like ERR_CERT_DATE_INVALID.

Fix

• Check the certificate’s expiry date using tools like SSL Labs or by clicking the padlock icon in your browser.
• Renew your SSL certificate from your Certificate Authority (CA).
• If you’re using Let’s Encrypt, set up automatic SSL renewal with Certbot or another ACME client.

Pro Tip: Always enable auto-renewal to avoid downtime due to expired certificates.

2. SSL Certificate Not Trusted by the Browser

If your certificate is not issued by a trusted CA, browsers won’t recognize it. This often happens when using self-signed certificates.

Symptoms

• Error: NET::ERR_CERT_AUTHORITY_INVALID
• Visitors cannot access your site without bypassing warnings.

Fix

• Purchase or obtain a free SSL certificate from a trusted Certificate Authority like Let’s Encrypt, DigiCert, or Sectigo.
• If using a self-signed certificate for internal testing, add the certificate to your trusted root store.

3. Mixed Content Warnings

Mixed content occurs when your site loads over HTTPS but includes resources (images, scripts, CSS) from HTTP URLs.

Symptoms

• The padlock icon appears broken or missing.
• Warning in browser console: Mixed content detected.

Fix

• Update all resource URLs to use HTTPS instead of HTTP.
• Use relative URLs (e.g., /images/logo.png instead of http://yourdomain.com/images/logo.png).
• Apply Content Security Policy (CSP) headers to block insecure requests and fix SSL issues.

Tools like Really Simple SSL (WordPress plugin) or Why No Padlock can help identify mixed content.

4. SSL Certificate Name Mismatch

This occurs when the domain name in the SSL certificate does not match the site’s domain.

Symptoms

• Error: ERR_CERT_COMMON_NAME_INVALID
• Occurs often with www vs non-www versions or subdomains.

Fix

• Ensure your SSL certificate covers all variations of your domain (example.com, www.example.com, sub.example.com).
• Consider using a Wildcard SSL certificate or SAN (Subject Alternative Name) certificate for multiple domains/subdomains.
• Update server configuration (Apache, Nginx) to use the correct certificate.

5. Incomplete Certificate Chain

SSL certificates rely on a chain of trust. If the intermediate certificates are missing, browsers can’t verify authenticity.

Symptoms

• Error: Unable to get local issuer certificate.
• The website works on some browsers but not all.

Fix

• Download and install the intermediate certificates provided by your CA.
• Configure your server to serve the full certificate chain (root, intermediate, leaf certificate).
• Test your SSL configuration using SSL Labs Test.

6. Incorrectly Installed SSL Certificate

If your SSL installation is incomplete or misconfigured, your site won’t load securely.

Symptoms

• Browser still shows “Not Secure” despite SSL installation.
• Errors in server logs during SSL handshake.

Fix

• Double-check your web server configuration (Apache, Nginx, LiteSpeed, IIS).
• For Apache: ensure SSLCertificateFile, SSLCertificateKeyFile, and SSLCertificateChainFile are properly set.
• For Nginx: ensure ssl_certificate includes the full chain.
• Use online SSL checkers to validate installation.

7. Server Misconfiguration

Even if your certificate is valid, server misconfiguration can break SSL connections.

Symptoms

• TLS handshake errors.
• Website fails to load on certain devices or browsers.

Fix

• Enable modern TLS protocols (TLS 1.2, TLS 1.3).
• Disable outdated protocols like SSLv2, SSLv3, TLS 1.0, and TLS 1.1.
• Ensure strong cipher suites are enabled.
• Use server hardening guides for Apache/Nginx to avoid weak encryption.

8. Old Protocol or Cipher Issues

If your server uses outdated cryptographic algorithms, some browsers will block the connection.

Symptoms

• Error: SSL Handshake Failed.
• Works on old browsers but fails on modern ones.

Fix

• Update your server to use TLS 1.2 and TLS 1.3 only.
• Remove weak ciphers like RC4 and 3DES.
• Test your server with SSL Labs to confirm modern security compliance.

9. Revoked SSL Certificate

SSL certificates may be revoked by the CA if compromised or misused.

Symptoms

• Error: NET::ERR_CERT_REVOKED.
• Website becomes completely inaccessible.

Fix

• Contact your Certificate Authority immediately.
• Request a new SSL certificate and replace the revoked one.
• Investigate the cause of revocation (e.g., compromised private key).

10. Browser or Device Cache Issues

Sometimes, the SSL problem isn’t with the server but with the browser cache or device.

Symptoms

• Site works on one device but not another.
• Visitors report inconsistent SSL warnings.

Fix

• Clear the browser cache and cookies.
• Restart the browser and device.
• Try in incognito mode or on another browser to confirm.

Best Practices to Prevent SSL Issues

• Always enable auto-renewal for certificates.
• Use Let’s Encrypt for free, automated SSL management.
• Keep your server software updated (Apache, Nginx, OpenSSL).
• Regularly test your site using SSL Labs or monitoring tools.
• Consider a Content Delivery Network (CDN) with managed SSL.

This guide will break down HTTP vs HTTPS, explaining their key differences, advantages, and why making the switch to HTTPS is crucial for your online presence.

What is HTTP?

HTTP stands for HyperText Transfer Protocol. It’s a standard protocol that allows communication between your browser and web server. When you visit website starting with “http://”, your browser requests data from server, and server responds by delivering web page.

For example:

• When you type ‘http://example.com’ into your browser, the server sends back requested page without encrypting the data.

While HTTP is straightforward and fast, its major flaw lies in lack of security. Any data sent over HTTP is transmitted in plain text, which means hackers or malicious actors can easily intercept it.

What is HTTPS?

HTTPS stands for HyperText Transfer Protocol Secure. It is essentially HTTP with encryption, adding extra layer of security using SSL/TLS certificates.

When you see website with “https://” in the URL, it means:

• All communication between your browser and server is encrypted.
• Sensitive information (like credit card numbers, login credentials, or personal details) is protected from interception.
• The website is verified with SSL/TLS certificate, which confirms its authenticity.

In short, HTTPS ensures that your connection is private, secure, and trustworthy.

The Core Difference Between HTTP and HTTPS

The primary difference between HTTP and HTTPS  down to encryption and security.

• HTTP: Data is transferred in plain text, which can be intercepted.
• HTTPS: Data is encrypted using SSL/TLS, making it unreadable to third parties.

This seemingly small difference has massive implications for privacy, trust, and search engine ranking.

Why HTTP is No Longer Safe

In the past, HTTP was acceptable because most websites didn’t handle sensitive data. But today, with online shopping, banking, and data-driven apps, HTTP is a risk.

Here’s why:

• Hackers can use techniques like man-in-the-middle attacks to steal your data.
• Passwords, payment details, and personal information can be exposed.
• Modern browsers like Chrome, Firefox, and Safari now warn users when they visit an HTTP site, labeling it as “Not Secure”.

This warning alone can scare away visitors and harm your website’s credibility.

Advantages of Using HTTPS

Switching from HTTP to HTTPS offers several benefits:

1. Enhanced Security: All communication is encrypted, protecting sensitive information from hackers.

2. Improved User Trust: Users feel safer browsing site that shows padlock symbol in the URL bar.

3. Better SEO Rankings: Google has officially confirmed that HTTPS is ranking factor. Secure websites are prioritized in search results.

4. Protection from Phishing: SSL certificates verify your site’s identity, reducing the risk of fake or fraudulent sites impersonating your brand.

5. Faster Performance: With modern protocols like HTTP/2, HTTPS websites often load faster than HTTP.

Common Myths About HTTPS

There are few misconceptions about HTTPS that need clearing up:

• HTTPS slows down websites: False, With HTTP/2 support, HTTPS is actually faster in many cases.
• Only e-commerce websites need HTTPS: False, With HTTP/2 support, HTTPS is actually faster in many cases.
• SSL certificates are expensive: Not anymore. Services like Let’s Encrypt provide free SSL certificates, making HTTPS accessible for everyone.

Understanding SSL Certificates

What is an SSL Certificate?

An SSL certificate encrypts the data exchanged between a browser and a server. This prevents attackers from intercepting sensitive information like credit card numbers, login credentials, and personal details.

Types of SSL Certificates

• Domain Validated (DV): Quick, cost-effective, ideal for blogs and small sites.
• Organization Validated (OV): Includes business verification, recommended for company websites.
• Extended Validation (EV): Provides the highest trust level with a green address bar.
  

How SSL Certificates Work

SSL uses a process called the handshake, where the browser and server exchange keys to establish a secure connection. While this adds microseconds of processing, the overall impact is minimal with modern hardware and optimized servers.

With SSLForWeb, securing your web application is quick and easy. It provides free SSL certificates with automatic installation and renewal, ensuring encrypted, safe connections for your visitors.

SSL and Website Performance

The Impact of SSL on Loading Speed

Years ago, SSL certificates were accused of slowing down websites. Today, the difference is almost negligible thanks to HTTP/2, TLS 1.3, and optimized hosting environments.

Common Myths About SSL Speed

Myth 1: SSL slows down your site.
Truth: With modern TLS and proper setup, the speed impact is almost zero. In fact, features like HTTP/2 and TLS 1.3 can even improve performance.

Myth 2: Free SSL is slower than paid SSL.
Truth: Both use the same encryption standards. Speed depends on server optimization, not whether the certificate is free or paid.

Factors That Influence SSL Speed

Handshake Process and Latency

The SSL handshake establishes trust but requires extra communication. Optimizing server response time can reduce this latency.

Encryption Strength and Processing Power

Stronger encryption (e.g., 2048-bit keys) is more secure but slightly heavier on processing. Choosing the right balance is essential.

Server Location and Configuration

Proximity of the server to the end-user significantly affects performance. Using a CDN (Content Delivery Network) can help.

Balancing Security and Speed

Best Practices for SSL Optimization

• Use TLS 1.3 for faster handshake.
• Enable HTTP/2 or HTTP/3 for improved parallel requests.
• Reduce redirects to save milliseconds.

How to Choose the Right SSL Certificate

Pick an SSL certificate based on your website type and trust level required. For example, an e-commerce store should invest in EV SSL.

CDN and Caching Strategies

CDNs cache encrypted content closer to the user. This ensures global visitors enjoy faster performance without compromising security.

Case Study: How SSL Impacts E-commerce Websites

E-commerce websites process sensitive transactions daily. Studies show that shoppers trust SSL-secured sites more. At the same time, optimized SSL ensures checkout speed isn’t compromised. A delay of even one second can reduce conversions by 7%, making SSL speed optimization crucial.

In this article, we’ll dive deep into how SSL improves SEO and website traffic, why it’s a must-have, and how you can implement it for the maximum impact.

What is SSL and Why Does It Matter?

SSL, short for Secure Sockets Layer, is technology that encrypts connection between website and its visitors. When site has SSL, you’ll notice little padlock icon in browser’s address bar and URL starting with https:// instead of http://

Here’s why SSL matters:

• Data Encryption: Protects sensitive information like passwords, credit card numbers, and personal data.
• Authentication: Ensures users are communicating with real website, not impersonator.
• Trust Building: Visitors feel safe, which increases engagement and conversions.

But security isn’t only benefit. Google officially announced in 2014 that HTTPS is ranking factor, which means SSL has direct effect on your SEO.

SSL as a Google Ranking Factor

When Google first introduced HTTPS as ranking signal, it was considered as “lightweight” factor. However, in recent years, as cybersecurity threats increased, Google has placed even more emphasis on secure websites.

• Websites with SSL often outrank those without it.
• Google Chrome labels non-HTTPS sites as ‘Not Secure‘, which discourages users from visiting.
• Secure websites get slight SEO advantage, helping them compete better in crowded niches.

In other words, if your competitor has SSL and you don’t, you’re already at disadvantage.

How SSL Increases Click-Through Rates (CTR)

SEO isn’t just about ranking, it’s also about how many people actually click on your website. SSL plays a role here too.

Imagine searching for product on Google. You see two websites:

• Site A: HTTPS with padlock icon.
• Site B: HTTP with warning that says ‘Not Secure’.

Which one are you more likely to click?

Most users instinctively trust secure sites. As result, websites with SSL certificates see higher CTRs, which sends positive signal to Google and can improve rankings even further.

SSL Improves SEO, User Trust and Engagement

Modern internet users are cautious. They want to know their data is safe before they:

• Fill out form
• Subscribe to a newsletter
• Enter payment details
• Download a resource

If your site doesn’t have SSL, users may bounce quickly, which increases your bounce rate. A high bounce rate tells Google that your website isn’t meeting user expectations, which can hurt your SEO.

On the other hand, SSL creates a sense of trust, encouraging visitors to stay longer, engage more, and convert, factors that indirectly boost your rankings.

SSL Boosts Local SEO Rankings

For businesses that rely on local customers, SSL is even more important. Local SEO depends on trust, credibility, and visibility. Secure websites are more likely to:

• Rank higher in Google Maps and local packs.
• Gain trust from local users searching for services.
• Convert local visitors into paying customers.

If you’re local business, SSL is not optional, it’s essential.

How to Implement SSL Correctly

Installing SSL is easier than ever. SslForWeb provides free SSL certificates for your websites. You can easily generate SSL Certificate using SslForWeb.

Here are few tips to implement SSL correctly:

• Redirect all HTTP URLs to HTTPS using 301 redirects.
• Update internal links to HTTPS.
• Check for mixed content issues (HTTP resources on an HTTPS page).
• Verify your HTTPS site in Google Search Console.

Done right, this ensures your SSL migration boosts SEO instead of causing issues.

FAQs

These days, SSL is no longer an option but a must-have for every website owner concerned with security and user trust.

How SSL Works

At its core, SSL works like a digital lock and key. When you connect to a website with HTTPS, the browser and the server perform a secure handshake. During this process:

1. Data is encrypted before it leaves your device.
2. The server decrypts it only after verifying the SSL certificate.
3. Hackers trying to intercept will only see scrambled information.

This is the difference between HTTP (insecure) and HTTPS (secure). Simply put, HTTPS is the safe version of the internet highway.

Types of SSL Certificates

Not all SSLs are created equal. Here are the main types:

• Domain Validation (DV): Quick and easy, verifies domain ownership.
• Organization Validation (OV): Adds company details, improving trust.
• Extended Validation (EV): The highest level of validation, shows company name in the browser bar.
• Wildcard SSL: Protects your main domain and unlimited subdomains.
• Multi-Domain SSL (SAN): Covers multiple domain names under one certificate.  

Why SSL is Essential for Your Website

• Data Protection: Prevents sensitive information from being stolen.
• Trust Building: Visitors feel safe when they see the padlock icon.
• SEO Benefits: Google boosts HTTPS websites in rankings.

Without SSL, your site risks losing both customers and search visibility. 

SSL and Website Performance

Some worry SSL slows websites down. The truth? Modern SSL protocols are optimized for speed. In fact, using HTTP/2 with SSL can make your website faster.

To keep performance high:

• Use a reputable SSL provider.
• Enable OCSP stapling.
• Regularly test your site speed.

Best Practices for SSL Security

• Always use HTTPS: Force all traffic through HTTPS.
• Enable auto-renewal: Never let your SSL expire.
• Redirect HTTP to HTTPS: Prevent duplicate content issues.
• Fix mixed content: Ensure all images, scripts, and links load via HTTPS.

Choosing the Right SSL Certificate

If you’re just running a blog, a free SSL like Let’s Encrypt works fine.
For businesses or e-commerce sites, invest in OV or EV certificates for higher trust.

Keeping Your SSL Updated

SSL certificates expire, usually every 90 days to 2 years. Forgetting renewal can cause your site to show scary browser warnings. Use automation tools or your hosting panel’s auto-renew option.

Testing Your SSL Setup

You can test your SSL setup using:

• Qualys SSL Labs
• Why No Padlock
• SSL Checker

These tools help identify weak ciphers, expired certs, and misconfigurations.

The Future of SSL and Website Security

Encryption standards keep evolving. TLS 1.3 is now the industry standard, providing lightning-fast security. With the rise of cyber threats, SSL will remain the foundation of web security for years to come.
 

Conclusion

SSL is no longer just a nice-to-have feature, it’s the backbone of online security. From encrypting sensitive data to improving SEO rankings, SSL protects both your website and your visitors. By following the best practices outlined above, you’ll not only build trust but also safeguard your digital presence against modern cyber threats.

In this guide, we will walk you through everything you need to know about renewing an SSL certificate, step by step.

What Is an SSL Certificate Renewal?

An SSL certificate renewal is the process of extending your website’s SSL validity once the old certificate is about to expire. Just like your passport or driving license, an SSL certificate has an expiry date. If not renewed, your website will:

• Display browser warnings (like “Not Secure”).
• Lose encrypted communication.
• Potentially harm your SEO rankings.

That’s why it’s crucial to renew before expiry.

Why Is SSL Renewal Important?

SSL certificates don’t last forever. Here’s why timely renewal is important:

1. Maintains Security: Protects sensitive data such as login credentials, personal information, and payment details.
2. Builds Trust: Keeps the padlock symbol visible, ensuring visitors feel safe on your website.
3. Avoids Downtime: Prevents disruptions in website functionality caused by expired SSL.
4. Boosts SEO: Search engines like Google prioritize websites with valid SSL certificates.

Step-by-Step Guide: How to Renew an SSL Certificate

Renewing your SSL certificate is simple when done correctly. Follow these steps:

• Navigate to the SslForWeb. In the SSL section, you can see the total number of SSL certificates that you generate, with the expiry date and the status, as you can see in the image below.

• Please note that in SslForWeb, you’ll need to generate a new SSL certificate for any domain whose certificate has expired.
• From the SSL section, click on the Create SSL button.
• Enter your domain name. You can enter the domain name with www. or without www., for example, I’m using here “mywpapp.salite.site”. If you have any subdomains, you can it here by separating them with a comma. 
• Select verification type from HTTP and DNS. Please note that if you create a wildcard SSL, the default selected verification type is DNS.
• Accept the checkbox to create an SSL Certificate and click on the Create button.

If you select DNS as a verification type:

• Log in to your account from where you host your domain.
•  Go to the DNS record settings and create a new TXT record. 
• In the Name field, enter the domain TXT record that will be mentioned in your dashboard.
• In the Value field, enter the verification code that will be mentioned on your dashboard.
• Wait for a few minutes for validation and click on the “Check” button. If you have multiple entries, make sure to check for all of them and click on the Validate Domain button.
• That’s it! Your SSL certificate is generated.

If you select HTTP as a verification type:

• Download the given file from the dashboard.
• Navigate to the root folder of your domain. If you are managing servers and applications from ServerAvatar, you can easily use the File Manager to navigate to the root folder and complete the process.
• Create a “.well-known” named folder in the root folder of your site, and inside the “.well-known” folder, create another folder named “acme-challenge”. 
• After that, upload the file that we downloaded previously inside the acme-challenge folder.
• Simply click on the link given in step 3 to check if it opens with random characters or not, and click on the check button to verify the status.

• Just click on the Validate Domain button.
• You can see that the SSL certificate has been generated. Now, you can simply use the generated SSL certificate to secure your site.

What Happens If You Don’t Renew?

If you fail to renew your SSL certificate:

• Visitors will see a “Not Secure” warning.
• E-commerce transactions may fail.
• Your website may experience a drop in conversions.
• Search engines may penalize your ranking.

In short, not renewing your SSL can cause serious security and business risks.

For SSL to work, a valid SSL certificate must be installed on the server. Depending on the type of certificate, it may be issued by a Certificate Authority (CA) or self-signed.

While SSL is an important security measure, certain SSL issues can arise if not properly configured. Below are five of the most common SSL issues and how to avoid them.

1. Faulty Installation

A faulty installation is one of the most common SSL issues. It can happen for various reasons, such as incorrect server configuration or an outdated root certificate. In some cases, it can even be caused by malware on the server. Whatever the cause, faulty installation can lead to serious security vulnerabilities. 

One way to avoid faulty installation is to use a reputable SSL provider. A good provider will offer comprehensive installation instructions that are easy to follow and provide 24/7 customer support in case you run into any problems. 

Another way to avoid faulty installation is to keep your server software up to date. This will help ensure that your SSL certificates are always valid and your server is configured correctly.

2. HTTPS Redirects

HTTPS is the secure version of HTTP, which powers most web traffic. When you visit a website over HTTPS, your connection to that site is encrypted, making it much more difficult for attackers to snoop on your traffic or interfere with your connection. Many websites have embraced HTTPS in recent years to improve security and privacy for their users.

However, HTTPS redirects can sometimes cause problems. If a website redirects from HTTP to HTTPS but doesn’t properly handle all the necessary details, it can lead to insecure connections or broken pages. As a result, it’s important to be aware of the potential issues that can arise from HTTPS redirects and take steps to avoid them.

Broken pages and insecure connections

One of the most common problems with HTTPS redirects is that they can break pages or result in insecure connections. This usually happens when a website redirects from HTTP to HTTPS but doesn’t properly handle all the necessary details. For example, if a website includes resources like images or JavaScript files that are still served over HTTP, those resources will not be loaded when the page is accessed over HTTPS. This can break the page or prevent it from loading entirely. Additionally, visitors may see browser warnings about insecure connections if a website’s SSL certificate is not properly configured.

To avoid these problems, ensure all resources on your website are served over HTTPS. This includes not only HTML pages but also any images, JavaScript files, stylesheets, etc. Ensure your SSL certificate is properly configured before enabling HTTPS on your site. You can use a tool like Qualys SSL Labs to test your site’s SSL configuration and identify potential issues.

Mixed content warnings

Another common problem with HTTPS redirects is mixed content warnings from browsers. Mixed content occurs when a page that is loaded over HTTPS includes resources that are served over HTTP. For example, if an HTML page on a website is loaded over HTTPS but includes images that are loaded over HTTP, those images will be considered mixed content. 

Mixed content warnings happen because browsers cannot verify the authenticity or integrity of mixed content resources. As a result, they display warnings to users to prevent them from loading those resources. These warnings vary depending on the browser; some browsers block mixed content by default, while others only display a warning message. 

To avoid mixed content warnings, ensure all resources on your website are served over HTTPS. If you’re not sure whether a resource is being served over HTTP or HTTPS, you can check using your browser’s developer tools; most browsers will display an icon next to each resource indicating its protocol (HTTP or HTTPS). Alternatively, you can use a tool like Mozilla’s Observatory to scan your website for mixed content and other potential security issues.

3. Expiration and Renewal Errors

One of the most common SSL issues is an expiration or renewal error. When an SSL certificate expires, it must be renewed for the secure connection to remain valid. If the certificate is not renewed, any data exchanged over the connection is at risk of being intercepted by third parties. To avoid this issue, set up email alerts so that you are notified well before the expiration date. It would help if you also had a plan for renewing the certificate so there is no lapse in coverage.

Invalid or incomplete certificate chain

Another common SSL issue is an invalid or incomplete certificate chain. A certificate chain consists of the server’s SSL certificate, as well as any intermediate certificates that are used to sign it. For the chain to be valid, all certificates must be signed by a trusted root authority, and none of them can be expired or revoked. To avoid this issue, check the validity of all certificates in the chain before installing them. You can use a tool like Certificate Inspector (https://sslmate.com/) to do this automatically. 

Revoked certificates

The issuing authority has invalidated a revoked certificate. This can happen for various reasons, such as if the private key associated with the certificate has been compromised. If you try to connect to a site using a revoked certificate, you will receive an error message telling you the certificate has been revoked. Check for revocation before connecting to any site using SSL to avoid this issue. Use a tool like SSLLabs (https://www.ssllabs.com/ssltest/).

4. Missing Hostname

A “missing hostname” error means that the domain specified in the SSL certificate does not match the domain where the certificate is being used. This can occur for various reasons, but typically it’s because the certificate was issued for a different domain than the one currently used. An example is if your site is hosted at www.example.com, but your certificate was issued for www.example.net, you would get this error. 

The best way to avoid missing hostname errors is to ensure that your SSL certificate matches the domain where it will be used. If you need to know which domain your site will be hosted at, you can generate a certificate with multiple domains (a Subject Alternative Names or SANs certificate). That way, if your site ends up being hosted at a different domain than you originally thought, you won’t need to worry about getting a new certificate – the SANs certificate will cover it. 

5. Insecure Signature Algorithm

An insecure signature algorithm is a flaw that can occur in the SSL protocol that allows for eavesdropping on communications. This issue arises when the signature algorithm used to sign the transmitted data needs to be stronger. As a result, someone can intercept the data and read it without being detected. 

Fortunately, you can take a few steps to ensure you are not using an insecure signature algorithm. First, make sure that you are using TLS 1.2 or higher. TLS 1.2 is the most recent version of the SSL protocol and contains many security improvements over previous versions. If you are using an older version of TLS, upgrade to TLS 1.2 as soon as possible. 

Second, make sure that you are using only strong cryptographic algorithms. Cryptographers have vetted strong cryptographic algorithms and proven to resist attack. Some examples of strong cryptographic algorithms include AES-256 and RSA-2048. 

Finally, keep your software up to date. Newer software versions often contain security fixes for known vulnerabilities, so installing updates as soon as they become available is important. By following these steps, you can help protect your communications from being eavesdropped on by third parties. 

What is an SSL Certificate Error?

An SSL certificate error occurs when your browser has trouble verifying the legitimacy of the website you’re trying to visit. The error usually appears as a warning message that says, “The site you’re trying to visit is not secure” or “This connection is not private.” Sometimes, you may even see a message saying the website’s security certificate has expired.

When you see one of these messages, your browser cannot verify that the website is what it claims to be.

How do I fix an SSL error?

The first step is to determine what type of SSL error you see. 

Check your network connection: Make sure that your computer is connected to the internet and that there are no problems with your network connection. 

Check your browser settings: Some browsers have strict security settings that can cause connection errors. Try changing your browser’s security settings to see if that fixes the problem. 

Clear your browser cache: Sometimes, cached data can cause problems with web connections. Try clearing your browser cache and cookies and see if that fixes the problem. 

Contact your ISP: If you’re still seeing errors, there may be a problem with your ISP’s servers or network infrastructure. Contact your ISP and let them know about the problem so they can investigate further.

2. Install Nginx On Ubuntu 22.04

If you have installed nginx, you can skip this. If you have not installed Nginx, then you click on this link: How to Install Nginx on Ubuntu 22.04 LTS

3. Create Nginx Virtualhost

First, create an Nginx virtual host to serve the HTTP version of the website.

sudo nano /etc/nginx/sites-available/<Your Domain Name>.conf

sudo nano /etc/nginx/sites-available/<Your Domain Name>.conf

Then, Use the below configuration for your website. Remember to change server_name, root, and fastcgi_pass based on your requirement.

server {   
    
  listen 80;   
  server_name sslforweb.ga www.sslforweb.ga;   
  root /var/www/html/sslforweb.ga;  
  
  location / {       
     index index.html index.htm index.php;   
  }  
  
  access_log /var/log/nginx/sslforweb.ga/logs/access.log;   
  error_log /var/log/nginx/sslforweb.ga/logs/error.log;   
  
  # Remove this section if the site hosts only plain HTML files  
  location ~ \.php$ {    
     include fastcgi_params;    
     fastcgi_intercept_errors on;    
     fastcgi_pass unix:/run/php/php8.1-fpm.sock;     
     fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;   
   }
}

server {   
    
  listen 80;   
  server_name sslforweb.ga www.sslforweb.ga;   
  root /var/www/html/sslforweb.ga;  
  
  location / {       
     index index.html index.htm index.php;   
  }  
  
  access_log /var/log/nginx/sslforweb.ga/logs/access.log;   
  error_log /var/log/nginx/sslforweb.ga/logs/error.log;   
  
  # Remove this section if the site hosts only plain HTML files  
  location ~ \.php$ {    
     include fastcgi_params;    
     fastcgi_intercept_errors on;    
     fastcgi_pass unix:/run/php/php8.1-fpm.sock;     
     fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;   
   }
}

Once you have created the virtual host configuration file, enable the website.

sudo ln -s /etc/nginx/sites-available/sslforweb.ga.conf /etc/nginx/sites-enable/sslforweb.ga.conf

sudo ln -s /etc/nginx/sites-available/sslforweb.ga.conf /etc/nginx/sites-enable/sslforweb.ga.conf

Next, Create a root directory to hold your website’s files.

sudo mkdir -p /var/www/html/sslforweb.ga/

sudo mkdir -p /var/www/html/sslforweb.ga/

Then, Change the ownership and group of the directory.

sudo chown -R www-data:www-data /var/www/html/sslforweb.ga/

sudo chown -R www-data:www-data /var/www/html/sslforweb.ga/

If you Finally, place the test HTML file on the website’s document root.

echo "This is a test site @ sslforweb.ga" | sudo tee /var/www/html/sslforweb.ga/index.html

echo "This is a test site @ sslforweb.ga" | sudo tee /var/www/html/sslforweb.ga/index.html

Then, restart the Nginx service to re-read the configurations.

sudo systemctl restart nginx

sudo systemctl restart nginx

4. Allowing HTTPS Through the Firewall

If the UFW firewall is enabled, as recommended by the prerequisite guides, you’ll need to adjust the settings to allow HTTPS traffic. Upon installation, Nginx registers a few different UFW application profiles. You can leverage the 443 port to allow HTTP and HTTPS traffic on your server.
To verify what kind of traffic is currently allowed on your server, check the status:

sudo ufw status

sudo ufw status

To allow for HTTPS traffic, allow the 443 port:

sudo ufw allow 443

sudo ufw allow 443

5. Online Generate Free SSL From SslForWeb

If you don’t have SSL Certificates, you can generate SSL for free through SslForWeb. Please refer this article: Generate Free Let’s Encrypt SSL Certificate.

6. Setup SSL On Nginx

This article will use a separate Nginx virtual host file instead of the default configuration file. We assume you already have a working nginx virtual host for your domain. We can run the command below to copy the sslforweb.com.conf configuration file to yourdomain.com-ssl.conf. Please change sslforweb.ga to your own .conf file in the command to ensure it runs properly.

sudo cp -a /etc/nginx/sites-available/sslforweb.ga{.conf,-ssl.conf}

sudo cp -a /etc/nginx/sites-available/sslforweb.ga{.conf,-ssl.conf}

Now we are going to store the certificate on the server.

First of all, Copy Certicate then run the below command:

sudo nano /etc/ssl/certs/sslforweb.ga.crt

sudo nano /etc/ssl/certs/sslforweb.ga.crt

Then paste it certicate and save the file. After, Copy Private Key then run the below command:

sudo nano /etc/ssl/private/sslforweb.ga.key

sudo nano /etc/ssl/private/sslforweb.ga.key

Then paste it private key and save the file.

Let’s edit the new virtual host ssl file.

sudo nano /etc/nginx/sites-available/sslforweb.ga-ssl.conf

sudo nano /etc/nginx/sites-available/sslforweb.ga-ssl.conf

Replace

listen 80;

listen 80;

In the first line with

listen 443;

listen 443;

Then, add these three lines:

ssl_certificate /etc/ssl/certs/sslforweb.ga.crt;
ssl_certificate_key /etc/ssl/private/sslforweb.ga.key;

ssl_certificate /etc/ssl/certs/sslforweb.ga.crt;
ssl_certificate_key /etc/ssl/private/sslforweb.ga.key;

Save the file then exit.

After this, we need to enable the SSL version of your site. We can run this command to enable the site:

sudo ln -s /etc/nginx/sites-available/sslforweb.ga-ssl.conf /etc/nginx/sites-enable/sslforweb.ga-ssl.conf

sudo ln -s /etc/nginx/sites-available/sslforweb.ga-ssl.conf /etc/nginx/sites-enable/sslforweb.ga-ssl.conf

At last, check your nginx configuration by running this command:

sudo nginx -t

sudo nginx -t

If everything is okay, then you will see the “Syntax OK” message, and you can restart Nginx.

sudo systemctl restart nginx

sudo systemctl restart nginx

Congratulations! At this point, you should be able to enable HTTPS protocol with Nginx on Ubuntu 22.04.
