[client crash]

I started a normal ARAM match and everything went smoothly until the loading screen didn't appear. I received an error saying that my firewall, which I haven't changed at all, was blocking the client or that the server wasn't working. Well, I went to go check the server status and everything was working besides a few champs being bugged and the Orianna skin being disabled. I kept trying to get into the game but kept getting the same error over and over so I restarted the client and it still didn't work. I restarted my computer and came back to see that I had afk'd a game and that I need to say "I agree" to not leave any future games. I will not be signing this as I didn't afk. Please fix the leaving system and the error. Thanks. I attached a puu.sh link that shows the afk message.
