Hey, I was playing destiny for a couple hours earlier today and right as an activity ended the game crashed on my pc and when I went to start it up and join a friend, it said that my NAT was on moderate when before it was on open. I have contacted my ISP and they can't seem to find an issue to what caused it to change. Testing NAT type on my Xbox Series X says my NAT is open. Only does it show moderate on my PC. I am not sure what happened or how to fix this problem.
