Cannot play call of duty aw on 2 consoles on same network

Well as the title says. I have 2 xbox 1 consoles in the same house on the same network. Here is the thing. If both consoles are playing independent of each other then there is no lag and everything is fine. But if we try to connect on the same host then
it either takes ages to find a game or if we do get one a game it boots us back to lobby menu. We have tried to connect mid game but I boots us again. The xbox down stairs is port forwarded and both have open NAT. Any suggestions.

Oh and playing Minecraft all together is not a problem.

Getting the same message on call of duty AW

 

Xbox One UPnP vs Port forwarding

DO NOT enable UPnP and forward ports. It will cause conflicts.

If you have multiple consoles on the same network and are trying to connect to Call of Duty AW,

You need to open additional ports to get an Open NAT.

Disable UPnP and open 3075 along with the other necessary ports for 1 additional console. If you have 2 additional consoles, open 3075 and 3076. UDP

 

Hey there, Fidge376! I'm very sorry to see that you were unable to launch up Advanced Warfare on two different consoles! I wanted to pop in and let you know that this is now resolved, and you should be able to launch up your game. If you run into this again,
please do post back so that we can look into this further if needed. We really appreciate your patience while we work on getting Advanced Warfare working again!

 

Cool but what I mean is that if me and my wife play on this console and my son try's to join the host from another xbox 1 then either we cant find a game or it crashes upon map loading. But playing independently. Is fine
