Ejected from games since the new patch

Hi Since the patch 4.19 when the game is loading in 5v5 I reach 100% and then I have a message : "you have been disconnected"... I relog and try ti reconnect, and after charging 100% it says the same thing... I tryed to reconnect at least 15 times... It's my computer bug or my connexion fail because all internet sites / videos works ...
