[Client] Logged out after every game + login screen changes?

Just started today, but after every game I'm given a "Failed to Reconnect" error and the client logs me out. When I try to log back in, it gives me another error just stating "There was a problem signing in etc etc". I can't log back in until about 10 or so minutes later, and only if I close the client and relaunch it. The strangest part is, when I launch the client back up my login screen is the "Welcome To League of Legends" background (the one with Poppy).

This has been happening after every game of ARAM I've played today. Instead of loading the Honor screen after a game ends, I just get the error followed by the login issues.
