Remote WSUS administration console connection error

[randle]

Hi,

 

I'm using the remote WSUS console from my computer on one subnet to connect to two different WSUS servers on two different subnets. I've managed to connect to one ok but the second one gives me the following error:

 

Cannot connect to 'ServerName'. The server may be using another port or different Secure Sockets Layer setting.

 

The WSUS server is running on port 80 and can connect to this via telnet so a little stumped as to why this isn't connecting. Connection traffic has been confirmed by the Firewall provider upstream so is getting through.

 

Any ideas?
