knowing that I have 2 network card and 1 pc laptop and that on 2nd computer I used another tale for me connect with teredo and that it still does not work I would like to know if you would have a script or a file an update teredo or an update of teredo itself
that I want to download to completely reset teredo

I'm having the same issue with party chats on pc not working bc the teredo is working even after trying to fix it with command prompt

After uninstalling the VPN service and the adapter that was created for it you need to follow the teredo fix steps from the beginning, also I recommend follow this steps

Open an Admin command prompt. In the command prompt type netsh interface Teredo set state disable.

Open up Device Manager. Go to View, then select Show Hidden Devices. Delete any network adapters with ‘Teredo’ in the name. You may have two showing, one named ‘Teredo Tunneling Pseudo-interface’ and one named ‘Microsoft Teredo Tunneling Adapter’.

Reboot the PC.

Re-enable Teredo by running the following command in an Admin command prompt: netsh interface Teredo set state >type=default.

Reboot the PC.

Keep me posted please

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, or if there’s software installed on your PC
that’s disabling Teredo functionality. Without a Teredo IP address, you’ll be unable to use party chat or do multiplayer gaming on Xbox Live.

Note The Teredo IP address is only necessary for Xbox Live party chat and multiplayer features. If your game doesn’t use the Xbox Live service, consult that game’s support site for help
on chat and multiplayer issues.
