[8.22]-Getting disconnected for no reason in several games

Since yesterday, I've been getting disconnected for no reason in ranked games, which turned them into losses even though I was carrying pretty hard. Everything starts being idle and I'm unable to do anything before I restart the whole client (logging in, etc...). This bug has nothing to do with personal reasons because it has also happened to my friend who plays 200 km away from where I live and he gets disconnected at the exact same time... We've also met a few players (always on our team) who had the same issue. Please fix this issue, I went from winning my gold promos to S1 0LP because I lost 4 games in which this issue happened. It even happened twice in one game...
