"The game has crashed". Cannot reconnect.

Had a game as TF, around 8:20 the "Attempting to reconnect" logo appeared, never came back so I decided to rejoin... But after I press reconnect this appears: "Unable to connect to server. Firewall may be blocking the connection..." After a while I'm able to reconnect, finished the game in a 3v2 (also happened to everyone) but after the game ended the "Game as crashed" screen is still here, if I press it, the "Unable to connect....." logo reappears, talked to a teammate after the game and he said that he didn't have it... I've tried the cmd flushdns thing, tried repairing the client, etc... I need help, I also read that people needed Riot to kick their account so they can play normally again? Is anyone else having this problem?

Edit: My account status still says I am "In Game"
