Client Game Ready Issue [CLIENT]

I have recieved a 20 minute leaver buster due to being afk in a game, which is fine.

The fact that I have waited 20 minutes for this and recieve a notification in the client saying ' An unexpected error has occured when loading Ready Chech. This has happened to me 2 times now, and I feel as if this needs to be fixed as I have been waiting and are still waiting over 40 minutes to find a game.
