I am stuck in playing a game of aram [Gameplay] [Client] **At the moment**

I cannot exit a game of aram.After the game finished I clicked "Leave without waithing for results" and got to end up on a "reconnect" button.When clicking it I get an internet error that tells me that connection cannot be made (but the client loads to blackscreen).After I restart the client and retry - my homescreen is still "reconnect" button. How can I end that game ?!****
