If a recent visit to some website has caused you to wonder what causes the \u201cNET ERR_CERT_COMMON_NAME_INVALID\u201d error on Google Chrome, you\u2019ve come to the right place to get all your answers!<\/p>\n\n\n\n

Certificate errors, along with their\nsecurity warnings, can leave us confounded and worried. This is particularly\ntrue in the current digital landscape where cyber-attacks are on the rise. The\nword on the street is that cybercriminals\nare already using HTTPS<\/a> to mislead users into believing their phishing\nwebsites are legit and secure. <\/p>\n\n\n\n

Considering that most netizens already\nconcerned about the security of their information, it doesn\u2019t help when they\nvisit a site and are greeted with an SSL error message. If you\u2019re a website\nowner, error messages can drive your sales down and cause reputational damages\nto your brand value. It is, therefore, vital that we take steps to resolve\nthese errors in a timely manner and retain the trust of customers. <\/p>\n\n\n\n

In this article, we\u2019ll take a look at the NET ERR_CERT_COMMON_NAME_INVALID error and attempt to understand why browsers flash this warning message. <\/p>\n\n\n\n

Let\u2019s get started by discussing the ERR_CERT_COMMON_NAME_INVALID chrome fix.<\/p>\n\n\n\n

How to Fix the NET ERR_CERT_COMMON_NAME_INVALID Error in Chrome<\/strong><\/h2>\n\n\n\n

The common name on your SSL certificate\nrefers to the domain name for which the certificate was issued. For example, if\nyou have a site www.mywebpage.com for which you’d like an SSL\/TLS certificate,\nthen the common name you would enter while filling out the certificate signing\nrequest (CSR) is mywebpage.com. <\/p>\n\n\n\n

The browser displays the “NET\nERR_CERT_COMMON_NAME_INVALID\u201d warning when the name on the SSL certificate does\nnot match the one in the address bar, or if there is a Chrome browser error. A\ncommon name mismatch happens if the domain on which the SSL certificate is\ninstalled is not listed on the certificate (either as a common name or subject\nalternative name [SAN], or covered under a wildcard). Additionally, a\nmisconfigured redirect could also be a potential trigger. <\/p>\n\n\n\n

To troubleshoot this error, we’ll have to\ntry a few different methods to identify and fix the issue. Before we begin,\nmake sure that the date, time, region settings are set up correctly. If they\naren\u2019t, they can create issues of their own. <\/p>\n\n\n\n

Next, let\u2019s look at fixing the error from the point of view of a website owner. We\u2019ll later discuss how to fix the NET ERR_CERT_COMMON_NAME_INVALID error code from the perspective of a site visitor.<\/p>\n\n\n\n

1. Does the Domain Have the Correct Certificate Installed?<\/strong><\/h3>\n\n\n\n

The most common reason for the error is a mismatch between the certificate and the domain name. Check if the cert secures the domain on which it’s installed. You can achieve this by inspecting the content of the certificate and comparing the domain on which the certificate is installed to the “Issued to” information (or the list of SANs on the SSL cert. Or, in case of wildcard certs, if the domain is covered by a wildcard).<\/p>\n\n\n\n

2. Check for Misconfigured Redirects<\/strong><\/h3>\n\n\n\n

Does your browser forcefully redirect visitors to another version of your website? Or does it force traffic over a www or a non-www connection? Note that not all SSL\/TLS certificates secure both www and non-www versions of a website, so you\u2019ll need to check that your current SSL cert is covering the version your site defaults to. Depending on the scenario, you may want to reconfigure your settings. Either you can eliminate the redirect or, if the redirect is necessary, you might need to obtain another certificate that covers the domain to which your traffic is being diverted.<\/p>\n\n\n\n

3. Ensure Your WordPress and cPanel Settings Are Configured Correctly<\/strong><\/h3>\n\n\n\n

For any site to be available over a secure HTTPS connection, you will need to have an SSL certificate installed. If you have a WordPress site, changing the site\u2019s protocol from HTTP to HTTPS will not automatically make your website available over a secure channel. <\/p>\n\n\n\n

\"WP<\/figure><\/div>\n\n\n\n

However, it can cause browsers to display the “NET ERR_CERT_COMMON_NAME_INVALID” warning. Revert the address to the old one, by editing your account\u2019s general settings, to get rid of the error message in the interim before you purchase an SSL cert.<\/p>\n\n\n\n

Once you\u2019ve made the changes in WordPress, navigate to phpMyAdmin in your cPanel dashboard and select the database for your relevant website. <\/p>\n\n\n\n

\"Phpmyadmin<\/figure><\/div>\n\n\n\n
\"WP<\/figure><\/div>\n\n\n\n

Select the wp_options and edit the site URL and home URL and ensure they have identical web addresses.<\/p>\n\n\n\n

Now, let\u2019s dive into the troubleshooting steps you can perform if you\u2019re a website user:<\/p>\n\n\n\n

1. Are Chrome Plugins or Browser Extensions Responsible for the Error?<\/strong><\/h2>\n\n\n\n

First and foremost, we need to identify the reason the error message is showing up. Once we have that figured out, we can apply the fix accordingly. Try accessing the website through the browser\u2019s incognito mode. If you don\u2019t encounter any error codes, and everything runs smoothly in private browsing mode, chances are one of your browser extensions are creating the problem. Head over to chrome:\/\/extensions\/ and activate each one individually and access the website. Once you find the plugin that\u2019s causing the error, you can remove or disable it. <\/p>\n\n\n\n

2. Clear Your Cache<\/strong><\/h2>\n\n\n\n

Corrupted cache or cookies can sometimes cause such error messages to appear in Chrome. To clear the cache, press the CTRL+SHIFT+Del keys on the keyboard and see whether this resolves the issue. <\/p>\n\n\n\n

\"Clear<\/figure><\/div>\n\n\n\n

You can also try\nclearing the SSL state. <\/p>\n\n\n\n

From the start\nmenu, type inetcpl.cpl<\/strong>. A dialog box named Internet Properties<\/strong>\nshould open up. Go to the content<\/strong> tab and select Clear SSL State<\/strong>.\n<\/p>\n\n\n\n

\"Clear<\/figure><\/div>\n\n\n\n

3. Check Your Proxy Settings<\/strong><\/h3>\n\n\n\n

Your proxy settings determine how your web traffic is routed. Any misconfigurations in your proxy settings can restrict your access to the web and can cause your browser to display a variety of warning messages. <\/p>\n\n\n\n

Under Internet\nProperties<\/strong> (you can access it as described in the previous step), go to the\nConnections<\/strong> tab. <\/p>\n\n\n\n

\"Check<\/figure><\/div>\n\n\n\n

Click on LAN settings <\/strong>and check the Automatically detect settings <\/strong>box. Uncheck other options and click OK<\/strong>.<\/p>\n\n\n\n

4. Update Your OS and Browser<\/strong><\/h2>\n\n\n\n

Outdated applications can have a host of security and compatibility bugs that can be sources of endless troubles. Double-check that you installed the latest updates for your operating system as well as the Chrome browser. <\/p>\n\n\n\n

As a last resort, you can enable HTTPS scanning in your antivirus or temporarily turn off your antivirus or firewall since these can sometimes block connections. However, it is never<\/em> a recommended practice to disable your firewall or to disable SSL warnings, but these fixes might temporarily let you access the website. They also leave you at great risk of falling victim to a multitude of cyber threats. <\/p>\n\n\n\n
