It pops up when there&#8217;s a mismatch between the domain name listed on a website&#8217;s SSL certificate and the domain you&#8217;re trying to visit. This security measure is crucial for ensuring that the site you&#8217;re visiting is actually the site it claims to be. It protects you from malicious sites trying to impersonate legitimate ones. However, when this error occurs, it acts as a red flag, potentially stopping you in your tracks and preventing access to the site. Understanding this issue requires a dive into the world of SSL certificates, encryption, and web security, all aimed at safeguarding our online interactions.<\/span><\/p>\n\r\n<style>\r\n  #ctablocks_inline_90{\r\n          background-color: #000000;\r\n        color: #ffffff;\r\n    border-radius: 6px;\r\n  }\r\n\r\n  #ctablocks_inline_90 p{\r\n    color: #ffffff;\r\n  }\r\n  #ctablocks_inline_90 .button{\r\n        background-color: rgb(51,57,241);\r\n      color: #ffffff;\r\n    border-color: #3339f1 !important;\r\n  }\r\n  #ctablocks_inline_90 .button:hover{\r\n    background: rgba(51,57,241,0.8);\r\n    color: #ffffff;\r\n    opacity: 1;\r\n  }\r\n        #ctablocks_inline_90 .ctablocks_content_info p {\r\n        padding-left: 36px;\r\n      }\r\n      #ctablocks_inline_90 .ctablocks_content_button {\r\n          margin-left: 37px;\r\n      }\r\n  @media screen and (min-width: 768px) and (max-width: 1260px) {\r\n      #ctablocks_inline_90 .ctablocks_content_button {\r\n          margin-left: 37px !important;\r\n      }\r\n  }\r\n  ;\r\n<\/style>\r\n<div id=\"ctablocks_inline_90\" class=\"ctablocks_container inline_type\r\n        \">\r\n\r\n  <div class=\"ctablocks_content clear\">\r\n    <div class=\"ctablocks_content_info\">\r\n      \r\n            <div class=\"title-wrap\">\r\n\t\t\t\t\t                  <img decoding=\"async\" src=\"https:\/\/10web.io\/blog\/wp-content\/uploads\/sites\/2\/2024\/04\/info-icon-cta.png\" alt=\"Say goodbye to website errors\" title=\"Say goodbye to website errors\">\r\n\t\t\t\t\t            <h4>Say goodbye to website errors<\/h4>\r\n        <\/div>\r\n              <p>Achieve peace of mind with 99.99% uptime on 10Web Managed <br>WordPress Hosting, powered by Google Cloud. <\/p>\r\n          <\/div>\r\n    <div class=\"ctablocks_content_button\">\r\n              <a href=\"https:\/\/10web.io\/ai-website-builder\/\" class=\"button\" data-gtag=\"sign-up-blog\" data-buttontype=\"sign-up\" data-gtag=\"cta-90\" data-buttontype=\"cta-inline\"\r\n\t        >Learn How<\/a>\r\n            \r\n    <\/div>\r\n  <\/div>\r\n    <\/div>\r\n\n<h2 id=\"variations-of-the-issue\"><span style=\"font-weight: 400;\">Variations of the issue<\/span><\/h2>\n<p><span style=\"font-weight: 400;\">This error can manifest in several ways across different browsers or devices, indicating the same underlying problem but presented with slight variations in the error message.

Here are the main reasons:<\/span><\/p>\n<p><b>Certificate name mismatch<\/b><span style=\"font-weight: 400;\">: The most direct cause is when the domain name on the certificate doesn&#8217;t match the address you entered. This can happen if the certificate is issued for a different domain or subdomain than the one you&#8217;re visiting.<\/span><\/p>\n<p><b>Certificate is expired<\/b><span style=\"font-weight: 400;\">: SSL certificates have a validity period. If the website&#8217;s certificate is expired, browsers will flag the site as insecure.<\/span><\/p>\n<p><b>Improper certificate configuration<\/b><span style=\"font-weight: 400;\">: If the certificate is not properly installed or configured on the server, browsers might not recognize it as valid. This includes missing intermediate certificates or misconfigured virtual hosts.<\/span><\/p>\n<p><b>Using a self-signed certificate<\/b><span style=\"font-weight: 400;\">: For internal testing or development environments, self-signed certificates are common. However, they&#8217;re not trusted by browsers unless manually added to a trust store, leading to this error.<\/span><\/p>\n<p><b>SNI (Server Name Indication) issues<\/b><span style=\"font-weight: 400;\">: Modern web servers use SNI to host multiple SSL certificates on a single IP address. If the server isn&#8217;t correctly configured to serve the right certificate for the requested domain, it can result in this error.<\/span><\/p>\n<h2 id=\"how-to-resolve-the-neterr_cert_common_name_invalid-error\"><span style=\"font-weight: 400;\">How to resolve the NET::ERR_CERT_COMMON_NAME_INVALID error<\/span><\/h2>\n<p><span style=\"font-weight: 400;\">Resolving this error is crucial in ensuring websites are accessible and for maintaining the trust of their visitors. Let\u2019s take a look at a comprehensive set of solutions to address and fix the problem.<\/span><\/p>\n<h3 id=\"make-sure-your-ssl-certificate-is-correct\"><span style=\"font-weight: 400;\">Make sure your SSL certificate is correct <\/span><\/h3>\n<p><span style=\"font-weight: 400;\">The `NET::ERR_CERT_COMMON_NAME_INVALID` error typically occurs when the domain name of the site a user is trying to access does not match the common name or any of the Subject Alternative Names (SAN) listed on the site&#8217;s SSL certificate. SSL certificates are used to secure communications between a user&#8217;s browser and the web server by encrypting data. A mismatch can occur due to various reasons, such as incorrect certificate configuration, changes in the domain name, or errors during certificate issuance. Verifying and correcting the SSL certificate&#8217;s details is a critical first step in resolving this error.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">To verify ssl certificate information:<\/span><\/p>\n<ol>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Open the problematic site in Google Chrome.<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Click on the <\/span><b>Not Secure<\/b><span style=\"font-weight: 400;\"> warning next to the URL bar.<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Select <\/span><b>Certificate (Invalid)<\/b><span style=\"font-weight: 400;\"> from the dropdown menu.
