I'm using the subjectAltName successfully though I am not using the wildcards. 
I'm using DNS:<hostname>, IP:<ip address>

Did you verify the subjectAltName was actually added on your signed 
certificate? openssl x509 -in <cert> -text

As far as I know, CN should be the fully qualified domain name. subjectAltName 
should have the wildcard.
