"Couldn't connect to server"

[MattKan]

Whenever I try to log into any server, I get the message "Couldn't Connect to Server" and get sent to the Login screen (before Login Server).

This is happening completely randomly; it was working fine. And I can see that nobody else is having problems, which is really weird. Also, it is happening on two computers, which both have been able to support Graal until now, so it's not a problem with my hardware.

If you guys have any tips to fix this, can you post in this thread, please? Thanks!
