Then, go to the IPv6 settings page in the router configuration.
You will see Allow Teredo tunneling and Allow IPv6 tunneling options there. Enable them by checking the boxes beside them. Save the changes and restart your router.

This should fix your error when you are trying to Test the multiplayer connection.

2] Turn on UPnP

Turning on UPnP fixes the NAT errors by changing the NAT type to Open NAT. It is done in the settings of your router.

To turn on UPnP on your router,

Log in to your router on a web browser using the address and credentials provided with the router.
Then, go to Advanced settings and select Advanced Setup of your router.
You will see Turn on UPnP there which is enabled by default. Check the box beside it to turn it off. Then, save the changes, restart your router, and then your console.
Now, go back to the Advanced setup of your router and check the box beside Turn on UPnP to enable it again. Save the changes and restart your router. Then, power cycle your router and Xbox console by disconnecting the cables for a few seconds and reconnecting them.

That’s it. It should fix the errors you are facing with NAT type and errors while joining party chat or multiplayer games.

Port 53 (UDP and TCP)
Port 80 (TCP)
Port 500 (UDP)
Port 3544 (UDP)
Port UDP 4500 (UDP)
