Unknown Error

Receiving many unknown errors while in champ select. Many things are happening during the champ select 1: The client will just spam unknown error and I can't do anything 2. Nothing will happen during the pick and ban phase, then I will just get booted although I can't do anything 3. When I enter a game, it'll say game not found or I failed to enter although I hit join Que (ARAM is fine) I play with other people on this internet and they do not have this problem, so that makes me uncertain as to what I should do. Thanks
