Firewall popup when joining a game.

So I was trying to play a game. I load then I get a popup disconnected. I restart league rejoin. Firewall blocking (i have no firewall). I restart comp and modem. I get same error over and over. I log onto my smurf and get rate into a custom game. So riot I have proof its not on my end. What the hell is wrong on your end that your client blocks one account but not the other from a firewall error when I dont even have a firewall.
