Typically the certificate uses an actual hostname as a "CN" value in its subject, so you'd need to specify the server URI using a hostname rather than an IP address to make sure that they match. If that's not what's going on here, please post a copy of the certificate that the server's using so that we can have a look. HTH, Nalin
