Hi there! This is Virginia O.

I understand that you are experiencing issues with your NAT being strict.

I apologize for the inconvenienced this has caused you. I will do my best to help you.

Please enable UPnP (Universal Plug and Play).

Access your router settings by typing your router's IP address into your web browser.

Log in with your router credentials.

Look for the UPnP settings and enable it.

Save the changes and restart your router and Xbox console.

And then Port Forwarding.

Access your router settings again.

Find the port forwarding section.

Enter the necessary ports for Xbox Live (you can find a list of required ports online).

Here are the list of the ports:

Port 88 (UDP)

Port 3074 (UDP and TCP)

Port 53 (UDP and TCP)

Port 80 (TCP)

Port 500 (UDP)

Port 3544 (UDP)

Port 4500 (UDP)

Save the changes and restart your router and Xbox console.

Next is to clear persistent storage.

Press the Xbox button on your controller to open the guide.

Go to Profile & system > Settings > General > Network settings.

Select Clear persistent storage and restart your console.

It is possible that the issue might be with your Internet Service Provider (ISP). Please reach out to them for assistance and ask if they can help you configure your network for better gaming performance.

Thank you for your cooperation and have a great day!
