Crash after champion select

Its S5 and there is a problem with my game. I noticed it when i got disconnected from a game, ignored it and tried reconnecting to multiple games after but the same issue occurred. Leauge would work fine when I open it, log in, enter the game, and enter champion select but after that the screen would turn black and read "Unable to connect to the server. If you have a firewall, it may be blocking the connection. Please refer to your firewall's documentation. Would u like to retry connection Retry| Cancel" . If i click retry it happens again and if I click cancel it would say that I'm still in game and i already was put into lower priority queue. I tried the Logitech "fix" where you place the "F" behind the full stop, tried deleting the files, reinstalling Leauge and repair in Leauge. None of the above worked any more suggestions? Or has this been happening to you?
