Just disconnected during loading (some network error) of ARAM, can't reconnect

Internet status = works. I immediately opened youtube and spotify to check.

What happened = got some sort of black screen with a pop up message about network. I say cancel, it sends me to the home page of the game. Then I click the play button, go back to an ARAM lobby, and I can't click Find Match anymore. Well I can but it doesn't do anything.

HELP

UPDATE: Tried to enter a practice tool game -> tells me i can't because I'm already in a game?!
