Whenever i start For Honor before i play with any of my friends my NAT is ALWAYS strict, however as soon as i get invited or invite a friend my NAT becomes open or moderate, and it stays this way till i restart the game. Ive gone through every single troubleshooting for connectivity, the game runs perfectly fine after i engage in playing with friends. There is absolutely no lag, the problem is the NAT on start up getting stuck on strict. What might be the cause? ive done port forward, UPnP, disable enable X,Y,Z and firewall exceptions, no firewall all of that.

Any ideas?

Edit: Only rarely does it swap off strict after about 1 hour or so of sitting doing nothing without getting an invite or inviting someone
