Steps to reproduce the problem:
1. Create a self-signed certificate with the common name "localhost"
2. Setup a web server with the certificate

What went wrong?
Chrome displays the "Your connection is not private" screen with the error code NET::ERR_CERT_COMMON_NAME_INVALID

Vis contradictory error description in screenshot: "This server could not prove that it is localhost; its security certificate is from localhost."

Did this work before? Yes 56.0.2924.87
