[Crash] [Gameplay] 6 of the 10 players in aram never connected!

So i decided to play some ARAM, got the varus and and was waiting to connect. it simply refused to show me the game even after connecting 100% 3 times. i restarted the patcher and client and got into the game. but it simply did not let me buy anything. Like i'd buy one thing and it gets returned immediately. Somehow i got a 'victory' in the game rather than a 'Leave'. Not complaining cause i totally tried to connect. Now that i check it, turns out that 6 of us 10 players never connected. 3 ebing on my team with thresh alone on opponent team which explains why the game was over quite fast.

If someone can please explain to me what happened i'd be grateful. I first thought it was some network issus though it seemed fine or maybe a LoL issue at my end. But 6 of us not connecting is serious.
