[CLIENT] Game not starting (for whole team)

I just had the weirdest bug ever. In Champ Select, (ARAM) the countdown ended but none of our teammates were able to play, because the game did not pop up. We sat there for a few minutes saying "????" then we all restarted the client, and I was able to see everyone was "In Champ Select" while we were not able to reconnect to the game. I dunno the reason for this, but as we waited the reconnect screen simply went back to the game home screen and there's no record of the game so I think the opposite team didn't get connected as well. I only have screenshots of my team chatting question marks.. Don't think that'll help. I hope I described it well enough.
