[CLIENT} Attempt to join queue failed.

I got this message after I had queued two times for a normal game(blind pick), but two people left before the game started from either our team or theirs, but I know I didn't leave at all. Then I tried queuing up again and got the message, even though I never left those pre-game lobbies or declined to join a game when it popped up. I don't know exactly how to replicate the error, as I'm assuming its something that shouldn't happen and it's the first time in my 2 years of playing that I've seen that notification. Just want to let you guys at Riot know that whatever system that controls that may be targeting players who get kicked out of a pre-game lobby because someone else left it, and its recording them as leaving it or something similar. Also for the record, i was solo-queuing, so it's not like I was with someone who was leaving.
