NET :: ERR_CERT_COMMON_NAME_INVALID error description

Don’t worry, if you own the website and you have a problem launching the account with the “NET :: ERR_CERT_COMMON_NAME_INVALID” error. We are here to help you with this failure. This article explores what and why the “NET :: ERR_CERT_COMMON_NAME_INVALID” error message is. We may also have different ways to resolve this error.

NET :: ERR_CERT_COMMON_NAME_INVALID

The common name of your domain name in an SSL certificate will be your web address. For example, your domain name would be site.com if you want to encrypt the site with an SSL certificate.

You can see all common variations of the site, WWW and non-WWW. Even a subdomain like mail.site.com can be a common name.

What are other word names and wildcards?

  • com.
  • site.com.
  • https://site.com and https://www.site.com.
  • http://site.com and http://www.site.com.

The common name can be the same as your web address and search screen. There will be common name errors if the name of the SSL certificate is not in the search / address bar with the site address.

Why does Chrome display “NET :: ERR_CERT_COMMON_NAME_INVALID”?

A common mismatch name is encountered when the SSL domain is not specified (either as a common name, alternate subject name, or wildcard). It is not the name of the domain that is built over SSL. It’s basically like you’re wearing the wrong hat on your blog.

There are also other explanations for why this message can appear, such as a failed directory, apart from the possible causes of “NET :: ERR_CERT_COMMON_NAME_INVALID” errors.

Process to clear the NET :: ERR_CERT_COMMON_NAME_INVALID error

You must first recognize what is causing the error. You can use any of these methods as a solution easily if you consider the reason:

  1. Make sure the domain has been correctly installed with the certificate

The most frequently mentioned cause seems to be the error “NET: ERR CERT COMMON NAME INVALID.” If the domain on which a certificate was issued is not included in the file, the file does not conform to the domain.

The best way to verify that the certificate will be verified and that the “given to” details relate to the domain the certificate is mounted on. However, in the case of certificates for SAN and wildcard, you can, as shown, search the SAN list (or find out whether the certificate domain has been installed according to the requirements covered by the certificate) on the certificate.

  1. WWW or non-WWW, check redirects

Determine if your browser is forcing visitors to the other variant of your website. If so, the settings will be changed to disable the switch. You may need to acquire a certificate to protect the domain to which you are forwarding traffic if this redirect is required.

You’ll also see if you’re forwarding traffic to a non-WWW site or domain update. This is relevant because the WWW and non-WWW variants of a web server are not protected by every SSL certificate; you must validate your certificate on each of the domain versions on which you have loaned money.

  1. Enter the appropriate parameter of your website address

Users are also confused about the protected URL and change the protocol on their website from unsecured HTTP to protected HTTP without purchasing and downloading SSL certificate. When you press Save changes, the following message will appear NET :: ERR_CERT_COMMON_NAME_INVALID. Fortunately, to get rid of this error message, you can quickly restore the web address to the old URL.

You can then go back to general settings with your WordPress account if you have a WordPress platform and search for the URL. If you accessed a protected version without purchasing or downloading the SSL certificate (for example by adding an “s” to the HTTP site), this would cause an error.

  1. Adjust your URL details in hosting via phpMyAdmin

You want to access your dashboard until you update your WordPress settings address without the protected version (HTTPS). In most cases, you don’t even have access to the login tab. So for newcomers this is the worst case scenario, now is the time to experiment with your hosting files.

  • Click on the ‘phpMyAdmin’ link to access the cPanel.
  • And then go to the database you like. (Be careful here: make sure you choose the right website across multiple sites).
  • Now you need to choose WP options – this is where you can change plugins and settings for WordPress themes (choose Wp options).
  • You will choose the URL and the home URL to edit the site. In both places, the web address must be the same. After unintentionally changing your URL in the WordPress settings field, you can indirectly go to the settings and adjust the username.
  • Update URL. You must upgrade your domain to HTTPS if you choose to use a protected protocol with the correct SSL certificate. You should change the HTTPS to HTTP before introducing SSL if you do not have SSL yet and are experiencing a privacy error issue.
  • Make sure your changes are saved after changing the URL. Since you’ve made improvements, properly verify changes on your site using the Chrome URL incognito window.
  1. Date of verification, date of check

Are your system date and time set correctly? Often times, minor things, such as setting the wrong time and date, can trigger major problems on your PC. This fundamental error can be corrected instantly.

  1. Disable antivirus

Web pages can be disrupted by antivirus or firewalls. Check if https scan in antivirus apps is not tagged with disabled. The only way out is to shut down the software if no other alternative is present.
