Hello SherpaDC, My name is David. I am an independent advisor, happy to help you today.

I'm sorry to hear that you're experiencing network issues when signing in on your Xbox Series X. Here are some possible causes and solutions you could try:

Network connectivity issues Although you mention that other devices on the same Wi-Fi network are working correctly, there may still be specific issues with your Xbox Series X's network connection. Try the following:

Restart your router and your Xbox Series X.
Verify that the Xbox Series X is connected to the correct Wi-Fi network and that the signal is strong.
Consider connecting your Xbox Series X directly to the router via an Ethernet cable to rule out wireless connectivity issues.
If possible, try a different Wi-Fi network to see if the issue persists.

Xbox Live account issues: There may be a problem with your Xbox Live account that is causing the sign-in errors. Try the following:

Verify that your login credentials (email and password) are correct. You can try to reset your password through the Xbox website.

Make sure there are no restrictions or blocks on your Xbox Live account, such as pending payments or suspensions.
Consider creating a new Xbox Live account temporarily to check if the issue persists. This will help determine if the issue is related to your specific account.
Network settings issues: Check the network settings on your Xbox Series X to make sure they are configured correctly. You can try the following:

Verify that the network settings on your Xbox Series X match the network settings on your router.
Make sure there are no firewall restrictions or MAC address filtering that could block your Xbox Series X from connecting.
Try resetting the network settings on your Xbox Series X and setting it up again from scratch.

Best regards.
