Client minimizing and not connecting to server

I turned off my computer last night. I turned it back on today after work and tried playing a game but the only thing that happens is my client minimizes to the tray and never connects to the game. I've tried logging out and logging back in with nothing. I've uninstalled and reinstalled the game.

I just lost two ranked games in a row because of this and will probably be penalized for AFK and be demoted. What the actual fuck?
