Halp needed random error unables me to play LoL

Hello, since patch 5.8 I find myself unable to play or getting into a game after 1 hour or trouble to even pick my champion. The issue I get is: when I enter a queue, example Normal Draft 5v5, I wait for a minute or 2, and then get unknwon error 3 times in a row or so and then it unables be to join a queue for 5 minutes until this happens enough times so I have to wait 15minutes... Or I get tired of waiting for a game and try to leave queue but it stays leaving queue for ages and never leaves and I get a ton of unknwon errors ad get disconnect from chat and tells me to hit "Reconnect" so I reconnect but the button never really shows up... Or randomly I get disconnected from chat... Or when I do accept a game (miracle) I end up seeing the bans, the first 3 players picking their champions and then the time runs out and it does nothing and I quit the client and when I'm back I have to wait some time to go back on a queue, when I happen to be one of the first picks I pick my champion, then the time runs out and I have to guess when the game has gone into loading screen since I'm trapped forever in champ select and I have to leave the client, login again, reconnect and join the game minutes after it has already started. I have looked everywhere, I have tried killing the "iphelper" service and it didnt help, tried repairing LoL, didnt help, tried reinstalling, didnt help, tried formating the computer, didnt help, tried disabling IPv6, didnt help, tried a stupid fix where adding a day on date/time of the computer would get me playing and it did, for one game, then it was back to the same deal... I'm giving up, I'm actually considering leaving the game alone all together...
