I started a game as 
, but when i was supposed to go to the loading screen it said " check your network" and i couldn't get on. my network is fine, i restarted the router and everything, and i couldn't get on, and it said the same message. By the way i could also do other things on the internet, like watch YouTube etc.
EDIT: i eventualy could join the game, but was around a min late to lane
Did you try turning it on and off?
I've been having the same issue since the preseason patch. I tried resetting my router, restarting client multiple times, and even tried the hextech tool that Riot support told me to try and I'm still having the same issue. Could a Riot staff please assist? Even after I finally get to connect 1-4 minutes into the game, depending on when it lets me connect, I have major lag spikes during the game (disconnecting/reconnecting) when I clearly have no internet problems. It just happens during matchmaking. I started a custom game by myself and I have no problem at all. It's just when I'm in matchmade pvp games.
