Hi,
Which port did you configure when setting up SSL?
A good troubleshooting step in this thread:
To test the HTTP application layer, open this URL in a browser on that console machine
http://wsusServerName/iuident.cab
If the browser launches a File Open/Save dialog for the CAB file, then the PROTOCOL layer is working correctly.
If the browser returns an HTTP 403 or HTTP 404, then a webfilter or proxy server is interfering with the HTTP protocol traffic.
The server may be using another port or different secure sockets (with a twist)

Hope this helps.
