I'm using US proxy because I always get "Server not responding" if I don't use it. And my SSH tunnel ends in California. The US proxy worked great, but if I disconnected in game (say I idled for too long or my SSH tunnel broke down while playing), sometimes I can't login again without quitting the whole game and restarting the launcher. It just says can't connect to the proxy. I'm sure my network is working.
What happened exactly? Had anyone else have this problem too?
