[Client] [Crash] I cant log into my account but surely my internet works!

I had logged in and started this game and then the game crashes. I try to reconnect but I cant. says trouble logging in. Says the reason can be found at a link but the link turns out to be a dead end. Help me here! I dont want to look like a leaver here but surely, this will be treated as a leave! Surely my internet works cause i opened up the link and also am reporting this to you right now. Please fix this! I dont want to get a time ban for something that isnt my fault.

Update: I connected now. The game was over and i got a Leave.
