I've been playing Destiny regularly since it came out, but all of a sudden a couple of days ago, I received a error message (caterpillar) when trying to start up the game. Now NOTHING allows me to successfully play. I can head into orbit, but the game displays a message saying I have a "strict NAT" (even though the Xbox One settings show an open NAT) and I'm kicked out with a caterpillar or cattle error message within a minute or two. I've tried port forwarding and resetting my router to factory defaults, but nothing works. Why did this problem show up all of a sudden? Is it really on my end? I can play other multiplayer games just fine.
