DescriptionChrome: 'Subject Alternative Name Missing' Certificate Warning
ScopeVersion: Chrome 58 and later
SolutionVersion: Chrome 58 and later
Issue: The "Subject Alternative Name Missing" certificate warning can also appear as a "NET::ERR_CERT_COMMON_NAME_INVALID" or "Your connection is not private" warning.
Solution: The Common Name of the certificate also needs to be listed as a SAN or else Chrome will complain. Chrome no longer looks at the Common name, only the Subject Alternative Names.
