"Connect To Server" Error

Hi all.

I have strange problem.I can not connect WSUS server.Whenever i try it gives me this error message "Cannot connect to 'Servername'.The server may be using another port or different secure sockets layer setting."I uninstalled whole WSUS with registry settings and clean install but nothing's changed.By the way when i open wsus console i can remote wsus server.

Server has Windows Server 2008 Standard SP2 and SQL Server 2005.
