Unknown Error

Ever since last patch from wednesday, I have not been able to stay online and play a game, it goes good for one game sometimes after that i get dc-ed and wont be able to log in and get unknown error which can take up to 2-5 hours before i can log in but i wont see game invites and i wont be able to queue for anything. It only happens on EUNE and never happens on WEST.

Unknown Error

An unknown error has occurred

Same error every time since the patch.

Any idea what i should do to change this?

edit: Also when i am logged in, when i swap from Champion / Match history / Profile, i get the same Error popping up and i got to press cancel on it like 20 times before it disapears.
