[CLIENT] An unexpected error occured while logging in. Please try again.

Whenever I try to log in I get "An unexpected error occurred while logging in. Please try again." If I try again, it sits on "Authenticating" for 5 minutes before giving me the same error. I've reinstalled, disabled firewall, started lol as admin etcetc still nothing works. It's beyond frustrating at this point I just wanna play some lol. Riot pls.
