Each of these problems can cause errors like\u00a0NET::ERR_CERT_COMMON_NAME_INVALID,\u00a0SSL Handshake Failed, or\u00a0Your 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.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><strong>1. SSL Certificate Has Expired<\/strong><\/h3>\n\n\n\n<p>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.<\/p>\n\n\n\n<p><strong>Symptoms<\/strong><\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Visitors see \u201cYour connection is not private.\u201d<\/li>\n\n\n\n<li>Browsers show error codes like&nbsp;<em>ERR_CERT_DATE_INVALID<\/em>.<\/li>\n<\/ul>\n\n\n\n<p><strong>Fix<\/strong><\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Check the certificate\u2019s expiry date using tools like SSL Labs or by clicking the padlock icon in your browser.<\/li>\n\n\n\n<li>Renew your SSL certificate from your Certificate Authority (CA).<\/li>\n\n\n\n<li>If you\u2019re using&nbsp;<strong>Let\u2019s Encrypt<\/strong>, set up&nbsp;<strong>automatic SSL renewal<\/strong>&nbsp;with Certbot or another ACME client.<\/li>\n<\/ul>\n\n\n\n<p><strong>Pro Tip:<\/strong>&nbsp;Always enable auto-renewal to avoid downtime due to expired certificates.<\/p>\n\n\n\n<p>You can use&nbsp;<a href=\"https:\/\/serveravatar.com\/\" target=\"_blank\" rel=\"noreferrer noopener\">ServerAvatar<\/a>&nbsp;to get a free automatic SSL Certificate with auto-renewals.

SSL Certificate Not Trusted by the Browser<\/strong><\/h3>\n\n\n\n<p>If your certificate is not issued by a trusted CA, browsers won\u2019t recognize it. This often happens when using self-signed certificates.<\/p>\n\n\n\n<p><strong>Symptoms<\/strong><\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Error:&nbsp;<em>NET::ERR_CERT_AUTHORITY_INVALID<\/em><\/li>\n\n\n\n<li>Visitors cannot access your site without bypassing warnings.<\/li>\n<\/ul>\n\n\n\n<p><strong>Fix<\/strong><\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Purchase or obtain a free SSL certificate from a trusted Certificate Authority like Let\u2019s Encrypt, DigiCert, or Sectigo.<\/li>\n\n\n\n<li>If using a self-signed certificate for internal testing, add the certificate to your trusted root store.<\/li>\n<\/ul>\n\n\n\n<h3 class=\"wp-block-heading\"><strong>3. Mixed Content Warnings<\/strong><\/h3>\n\n\n\n<p>Mixed content occurs when your site loads over HTTPS but includes resources (images, scripts, CSS) from HTTP URLs.<\/p>\n\n\n\n<p><strong>Symptoms<\/strong><\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>The padlock icon appears broken or missing.<\/li>\n\n\n\n<li>Warning in browser console:&nbsp;<em>Mixed content detected<\/em>.<\/li>\n<\/ul>\n\n\n\n<p><strong>Fix<\/strong><\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Update all resource URLs to use HTTPS instead of HTTP.<\/li>\n\n\n\n<li>Use relative URLs (e.g., \/images\/logo.png instead of&nbsp;<a href=\"http:\/\/yourdomain.com\/images\/logo.png\" target=\"_blank\" rel=\"noreferrer noopener\">http:\/\/yourdomain.com\/images\/logo.png<\/a>).<\/li>\n\n\n\n<li>Apply Content Security Policy (CSP) headers to block insecure requests and fix SSL issues.<\/li>\n<\/ul>\n\n\n\n<p>Tools like Really Simple SSL (WordPress plugin) or Why No Padlock can help identify mixed content.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><strong>4. SSL Certificate Name Mismatch<\/strong><\/h3>\n\n\n\n<p>This occurs when the domain name in the SSL certificate does not match the site\u2019s domain.<\/p>\n\n\n\n<p><strong>Symptoms<\/strong><\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Error:&nbsp;<em>ERR_CERT_COMMON_NAME_INVALID<\/em><\/li>\n\n\n\n<li>Occurs often with&nbsp;<strong>www&nbsp;<\/strong>vs<strong>&nbsp;non-www<\/strong>&nbsp;versions or subdomains.<\/li>\n<\/ul>\n\n\n\n<p><strong>Fix<\/strong><\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Ensure your SSL certificate covers all variations of your domain (example.com, www.example.com, sub.example.com).<\/li>\n\n\n\n<li>Consider using a Wildcard SSL certificate or SAN (Subject Alternative Name) certificate for multiple domains\/subdomains.<\/li>\n\n\n\n<li>Update server configuration (Apache, Nginx) to use the correct certificate.<\/li>\n<\/ul>\n\n\n\n<h3 class=\"wp-block-heading\"><strong>5. Incomplete Certificate Chain<\/strong><\/h3>\n\n\n\n<p>SSL certificates rely on a&nbsp;<strong>chain of trust<\/strong>. If the intermediate certificates are missing, browsers can\u2019t verify authenticity.<\/p>\n\n\n\n<p><strong>Symptoms<\/strong><\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Error:&nbsp;<em>Unable to get local issuer certificate<\/em>.<\/li>\n\n\n\n<li>The website works on some browsers but not all.<\/li>\n<\/ul>\n\n\n\n<p><strong>Fix<\/strong><\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Download and install the intermediate certificates provided by your CA.<\/li>\n\n\n\n<li>Configure your server to serve the full certificate chain (root, intermediate, leaf certificate).<\/li>\n\n\n\n<li>Test your SSL configuration using SSL Labs Test.<\/li>\n<\/ul>\n\n\n\n<h3 class=\"wp-block-heading\"><strong>6.
