Common name support was removed at version 58 of Chrome. It will only trust and allow access via https using a cert from a trusted CA. From: https://www.thesslstore.com/blog/security-changes-in-chrome-58/
"Many people don’t know that the “Common Name” field of an SSL certificate, which contains the domain name the certificate is valid for, was actually phased-out via RFC nearly two decades ago. Instead, the SAN (Subject Alternative Name) field is the proper place to list the domain(s).
However, this has been ignored and for many years the Common Name field was exclusively used. Chrome is finally fed up with the field that refuses to die. In Chrome 58, the Common Name field is now ignored entirely.
This means certificates that were exclusively using that field to indicate the valid domain name are no longer supported. Publicly-trusted SSL certificates have been supporting both fields for years, ensuring maximum compatibility with all software – so you have nothing to worry about if your certificate came from a trusted CA."
