For the past 4-5 days, everyday between 7 and 11p.m. CEST (probably later too) I kept getting "Unknown Error" while the client was trying to connect to the server I guess. When I restart the client it gets stuck at "Logging on", sometimes I somehow manage to log in after numerous tries but then when I get to the profile I can't see my division and champion masteries, I don't get game invites etc. I tried restarting the router and laptop, at the same time the game works just fine on the other laptop in my network. What's interesting, from the morning till the evening the game worked just fine everyday.
I hope someone helps me solve this problem as I'm unable to play with my friends xc
