502 Bad Gateway in game.
For some reason in the first 5 minutes of the game A white "webpage" went over my LoL game and said 502 Bad Gateway. I could still hear the sounds of the game before I closed it and attempted to reconnect. After reconnecting and continuing to play for a bit, it happened again. After closing the game and the client and restarting it didn't happen anymore. My cursor was still the league cursor, but I'm not sure if any commands I put in went through.
