If you own the website, you should convert to HTTPS and install an SSL certificate to secure the connection and protect visitors’ data. If you find that a given technique is not working for you, you can always try the next one down.

Method 2: Clear Browser Cache

Even if you’ve double-checked the configuration of the SSL certificate and the issue seems to be fixed, your browser may be showing a cached version of the homepage. It may help to delete the browser’s cookies and cache in this scenario.

If you’re using Firefox and have encountered the SSL ERROR BAD CERT DOMAIN problem, follow this brief tutorial to clear your cookies and cache:

Step 1: Launch Firefox and select Library from the menu that appears when you click the action icon in the upper right.

Step 2: Select Recent History and then click Clear.

Step 3: Choose Everything as the time range to clear and then choose the boxes labelled Cookies, Cache, and Offline Website Data. When you click OK, your selections will be removed.

Step 4: See if the error has been resolved by restarting Firefox when the process has finished.

Method 3: Configure Date and Time

The date and time on the computer are verified by Mozilla Firefox. The “Firefox error code ssl error bad cert domain” may appear if the system’s current time and date are very different from the server’s server time and date.

Verify that the time and date on your device are in sync with those of the internet.

Method 4: Verify Whether the SSL Certificate is Valid

The Firefox browser makes it easy to view the certificate’s details, including the issuing organisation and expiration date, for any website, regardless of whether you created it. This will tell you if the SSL_ERROR_BAD_CERT_DOMAIN is occuring because the SSL certificate for the domain in question has expired.
