This exception will be raised if the certificate returned by the
peer was issued for a different host than we tried to connect to.
This could be due to a server misconfiguration or an active attack.
@param expectedHost: The name of the host we expected to find in the
certificate.
@param actualHost: The name of the host we actually found in the
certificate.
@param fieldName: The field name where we noticed the error. This
should be either 'commonName' or 'subjectAltName'.
R t subjectAltNames@ Unknown fieldName, should be either commonName or subjectAltNameN( s
