Was there a solution to this issue? I have the same problem. New WSUS 6 install on Windows server 2012R2. Using WPP v1.3.1504.15.
I can connect by typing the FQDN but cannot connect with "connect to local server" selected. I do not have SSL enabled. When I connect with the "Connect to local server" option selected, I receive "Connection failed: Unable to connect to the remote server" and then "failed to connect to server".
I cannot add a certificate when connected to the FQDN even though I am logged in to the machine via RDP. The option to import a certificate is greyed out.
