I was away for a couple months, came back to play on the hardcore server because it sounded fun. Only been back for about a week and Ive noticed that about half the time when I log in I don't connect to the chat servers and I don't know why. Game seems to work fine, and whispers work, was able to run a couple quests with a full group by whispering the leader and everything except the chat seemed to work fine.

Is there something I can check to figure out why it sometimes works and sometimes doesn't?
