Yes, this has just happened to me right now and i was seeing why this was; i was around 10 or so minutes in and the game just stopped. I lost connection, At first i assumed it was my internet, but when i checked on speed-test i had 12 ping and 60 down. so i reset league and logged back in for around a good 2 minutes and got another double kill; the game was looking good for me, but just shortly after it disconnected again, but this time i couldn't log back in. I did everything I could think of and all the NEW client says is, "authenticating" and there is no way for me to log back in. I was recording the whole thing and i have many screenshots to back up my statements. "i don't like the new client"
