Firewalls Problems popping up again

The Firewall block is back and impossible for me to get past. The first time it popped up for me a good while back it at least let me get into the game after a little bit but now it won't let in the games at all. It's happened twice in not even 24 hours, and if it keeps up I'm going to just keep racking up 'leaver status' in my match history. The thing that bothers me most about that is that my team is just stuck without 1 or more person and that with the new **LeaverBuster **system it might actually ban me or put me in lower priority queues. It's completely ridiculous that this has started happening again randomly. Either some patch or way to fix it would be appreciated though. Being banned for something that is not my fault at all would be a little more than upsetting.
