Found by Justin Abrahams (iThemba Labs):

Suppose the hostname used by the server in its server cert does not match the result of a reverse DNS lookup done by the client. In that case, UAExpert shows a "BadCertificateHostNameInvalid" warning, while the IOC does not connect without giving an explanation.

It would be good to show some hint in this case.
