I just tried to start a 5v5 draft pick and when the game went and started loading a message popped up saying there was a problem with my firewall but this has never happened to me before. this is the first game I have played since the newest update. could that be the problem? And will I be banned because of this error? I have tried reopening league and trying reconnect but the problem about the firewall keeps on happening.

Bump, I had the same problem today, though I was lucky and managed to get back at 30 seconds until minions spawn. It was a blind 5v5 for me though.
