It looks like your server is no longer up. I had this same problem and the problem was with my realm config. The realm address was not routable from the outside. Make sure ultimateworldofwarcraft.servegame.org points to the correct IP and that port 8129 is forwarded to your computer.
When your server is running, open a command prompt and type:
Code:
telnet ultimateworldofwarcraft.servegame.org 8129
press enter and if it connects you should get something like:
If so you should at least get the realmlist when connecting to your server.
If the telnet connection times out then you have a routing problem. Either the dns isn't pointed correctly or the port isn't forwarded correctly. If you have a firewall the ports need to be opened on that as well.
If telnet is able to connect and you still can't get the reamlist when connecting then I don't know what your problem is. I might be able to send you my copy of the server if you want.
