What if the web browser, such as Google Chrome, displays the message “ERR_CERT_COMMON_NAME_INVALID” when we attempt to visit a particular website? In this case, it is impossible to visit the resource, because this particular error is associated with failures of the SSL/TSL certificate itself. The most common causes of “err cert invalid error” (common_name) are:

• The security certificate is not configured on the server-side. For example, the subject alternative name (SAN) extension is not tied to the certificate.
• Incorrect network settings in the user’s device like- time, date, time zone.
• Some extension of Chrome interferes with SSL / TSL certificate.
