Host - GrahamCCRL.dyndns.org Port - 16083

I've downloaded and installed the 'Tom's Live Chess Viewer' software. It opens fine and then I set the host to GrahamCCRL.dyndns.org and port to 16083.
When I connect ''Attempting to connect..." after a few seconds I get a message saying:
"Unable to connect to server"

The windows firewall is off. I can launch a command prompt and successfully ping GrahamCCRL.dyndns.org as follows

C:\Users\Me>ping GrahamCCRL.dyndns.org

Router permission settings perhaps?
Unfortunately I'm not a technical expert on such matters.

I really do wish that TLCV was more accessible, as many enthusiasts seem to strike problems trying to connect.
