Difference- Port in Mockservices vs Mock Port in SSL settin?

Having the same issue. Not able to have mock service running on the same port that is specified in Preferences->SSL Settings->Mock Port.
I've tried different ports (8443, 8989 etc). But not able to make mock service running on needed port. Restart of SoapUI or Windows is not helping.

Error details:
