This video will tell you what a name mismatch error is, how to identify it and what is the solution for it. It is displayed as NET::CERT_COMMON_NAME_INVALID.
Hello, I have the same error with my certificate, on the Microsoft Edge browser (I can only use it, didn't try with other browsers). My Common Name (CN) is exactly the same as the URL I'm using, but I'm receiving a "NET::ERR_CERT_COMMON_NAME_INVALID" error, and the padlock is not secure. Could this happen because my certificate has only CN populated, but it doesn't have any SAN (Subject Alternative Name)?
