Unable to create a lobby?

I just tried to get into a game and was in champ select, got the countdown to 0 and then the game didn't start and I suddently got a message saying sorry, unable to start your game.

After that I tried to create another lobby and got a message saying You are not eligible to create a lobby for this queue.

I tried this for every game mode but I get that message from every one of them. Does anyone have any idea why I'm getting that message or how to fix it? I tried relogging but that didn't help.

Edit: I played like 5 games before this happened so I have no idea what could've caused it.
