Ranked not working for me

So I tried to play a ranked game again today, and like yesterday my window vanishes after champ select and nothing loads. It cost me lp yesterday and appears it will cost me more today. Also, upon loading lol, I got a message saying afking during games was punishable. This is not my fault and I would like to keep playing but I can't enjoy the game as long as it won't ever load for me. Can you prevent me from getting punished and maybe tell me what I have to do to fix this?
