Teredo is a networking protocol that’s used to establish secure communications between clients and servers, and to facilitate connectivity between devices behind routers that use network address translation
(NAT).

Failure to obtain a Teredo IP address can occur when there’s an issue with your Teredo adapter, when a device on your network is blocking the Teredo protocol. Without a Teredo IP address, you’ll be
unable to use party chat or do multiplayer gaming on Xbox Live.

Check to see if Teredo connectivity is blocked when a VPN client is connected, or while a VPN network adapter is installed

Some VPN clients will disable Teredo connectivity while the VPN client is connected, and some VPN clients that install a network adapter that will disable Teredo until the VPN adapter is removed. If you’ve
installed a VPN client and Teredo is still disabled even while the VPN client is disconnected, check to see if you have a network adapter named
TAP-Windows Adapter V9 installed:

1. Right-click the Start icon, and then select Device Manager.
   
2. Select View > Show Hidden Devices.
3. Select Network Adapters.
4. Identify any adapters that have a name like TAP-Windows Adapter V9. Right-click the adapter name, and then select
   Uninstall.
   Note While uninstalling the VPN network adapter should unblock Teredo connectivity, this will also likely cause issues with the VPN client software. If you still require VPN functionality along with Teredo support, refer to the support documentation
   for the VPN client.
   

If you can’t hear your friends online, or you can’t join or host an Xbox Live multiplayer game, go to
Network > Settings in the Xbox app and check
NAT type.
