Annoying Bug

[jimmyplox]

Hey, just tried to play on this server again, select the realm and it freezes on "Connected".

How can I fix this? I have the right realms etc, firewall isn't the problem so I'm not sure what is the reason, all other servers work except this one, I use the custom launcher so I can run it and it downloads while I play.

for which Expansions/Realm you have this problem?
