But if this method doesn’t do the trick, you can try the next fix below.

2. Check the status of Teredo

If you’re getting the ‘Unable to connect to the live configuration servers’ error, it may be caused by a Teredo issue. Here’s how:

1) Click the Start menu (the Windows logo key) in the lower-left corner of the main screen.

2) Select Settings > Gaming, and then select Xbox Networking.

3) Select Fix it. Windows will try to detect and fix known issues with Teredo.

4) Once complete, you will need to click the Check again button. If there’s no issue detected, you can launch your game to check if the ‘Unable to connect to the live configuration servers’ issue disappears.

3. Reinstall the Teredo Adapter

It’s possible that the method above doesn’t fix the Teredo related issue, and you can try reinstalling the Teredo Adapter using Command Prompt. Here’s how:

1) In the Search bar, type cmd and select Run as administrator.

command prompt admin

2) Type the following command and press Enter.

netsh interface Teredo set state disable

3) On your keyboard, press the Windows + R key at the same time, and type devmgmt.msc. Then press Enter.

uninstall graphics driver

4) Click View > Show hidden devices.

5) Double-click on Network adapters.

6) Right-click any Teredo adapter and select Uninstall.

7) Go back to the Command Prompt (Admin) window, and enter the following command.

netsh interface Teredo set state type=default

8) Now launch your game and check if the error message ‘Unable to connect to the live configuration servers’ is gone for now.

4. Turn on Windows Firewall

You may have turned Windows Firewall to prevent some games from crashing, but this game requires that Windows Firewall is turned on because it will need the Teredo IPsec connection.

1) In the Search bar, type cmd and select Run as administrator.

command prompt admin

2) Type the following command and press Enter.

netsh advfirewall set allprofiles state on

3) Close the Command Prompt.

Launch your game again to test the issue, and if this method doesn’t do the trick, check the one below.

5. Enable Xbox Live Networking Service & Xbox Live Auth Manager

To make sure your game runs properly, you’d better check the Xbox Live Networking and Xbox Love Auth Manager services are both running properly. Here’s how:

1) On your keyboard, press the Windows key + R key at the same time, and enter services.msc.

2) Scroll down the bottom, and make sure Xbox Live Auth Manager and Xbox Live Networking Service are running. If not, right-click the service and click Start.

3) Close the window and launch your game.


Did the fixes above helped you out? If the ‘Unable to connect to the live configuration servers’ error persists, you may need to hard reset your router or Xbox One, uninstall and reinstall the game.
