Which login server are you using? Every time this comes up I remind people there are at least 3 login servers...
[LoginServer]
Host=eqemulator.net:5999
#Host=projecteq.net:5999
#Host=www.tsahosting.net:5999
Remove the # in front of the one you want to use (and put a # in front of the others).
Also change the port to 5998 if you're not using SoD client.
FWIW the first one (eqemulator.net) is working fine for me, on SoD.
