Windows 10: Teredo is running fine but still can't join the game

Windows 10 Pro 22H2, the game is Forza Horizon 4. I’ve made sure that I have the latest updates. And I don’t have any NI software or services by NI.The Teredo Tunneling Adapter is missing from my PC. I have tried to find it in the device manager but it is not there. I did select show hidden devices but it still does not show up. I then tried to install it from the device manager via add legacy hardware, but it does not show up in the list under the Microsoft section. When I run the command prompt and type ‘netsh interface Teredo show state’ it shows that Teredo is running but I still failed to

No Teredo installed

Hi Jay,

Thank you for writing to Microsoft Community Forums.

Before we proceed, could you please confirm a few things for me?

1. The make and model of your system?
   
2. The Windows 10 Build you are using?
   

Systems communicate with one another using a certain predefined set of protocols, when systems within a network are using different protocols but are trying to communicate with one another it may require a translator to enable
this communication. This is where the Teredo Tunneling comes in. It facilitates the connectivity between devices behind routers that use network address translation (NAT) and thus enable this communication.

Given that you have already tried to enable the Teredo through the device manager and the netsh command through the command prompt, we have a few more steps that we could try to resolve this issue.

Check and make sure that no VPN client is blocking the Teredo connectivity.

Steps:

Manually enable the Teredo through the registry.

Disclaimer: Important this section, method, or task contains steps that tell you how to modify the registry. However, serious problems might occur if you modify the registry incorrectly. Therefore, make sure that you follow these
steps carefully. For added protection, back up the registry before you modify it. Then, you can restore the registry if a problem occurs.

To take a backup or restore the registry click
here.

Check the iphlpsvc registry path:

1. Right-click the Start icon, type in cmd, Right-click on it and 'Run as administrator'.
   
2. Run the following command from the Admin command prompt: reg query HKLM\System\CurrentControlSet\Services\iphlpsvc\Teredo
   
3. If you find this output: Type REG_DWORD 0x4
   
   You will need to Re-enable Teredo by running the following command from the Admin command prompt: netsh interface Teredo set state type=default
   

Check the TcpIp6 registry path:

1. Right-click the Start icon, type in cmd, Right-click on it and 'Run as administrator'.
   
2. Run the following command from the Admin command prompt: reg query HKLM\System\CurrentControlSet\Services\TcpIp6\Parameters
   
3. If you find the output, and the value displayed is not 0x0. Example: DisabledComponents REG_DWORD 0x8e
   
4. You will need to Re-enable Teredo by running the following command from the Admin command prompt: reg add HKLM\System\CurrentControlSet\Services\Tcpip6\Parameters /v DisabledComponents /t REG_DWORD /d 0x0
   

Hope it helps.

Teredo Tunneling Pseudo-Interface Adapter Missing

Hello,



Thank you for writing to Microsoft Community Forums.



I would like to know the reason you are trying to install the Teredo Tunneling Pseudo-Interface Adapter, so that we can suggest you alternatives. If you are trying to install it for Xbox app on Windows Computer then we can have the dedicated team look
into it.



However here are some steps that you can try. To enable Teredo adapter:

• Right-click the Start icon, and then select
  Command Prompt (Admin).
  
• Run the following command from the Admin command prompt:
  
  • netsh interface Teredo set state type=default
    
• 
  

**The Microsoft Teredo Tunneling Adapter will reinstall automatically. Don’t install the Teredo Tunneling Pseudo-Interface adapter manually in Device Manager, as this may cause issues with Teredo functionality**



Also check to see if Teredo is disabled in the registry by a program or by a manually configured registry value.

• Right-click the Start icon, and then select
  Command Prompt (Admin).
  
• Run the following command from the Admin command prompt:
  
  • reg query HKLM\System\CurrentControlSet\Services\iphlpsvc\Teredo
    
  • If the output includes the following line, Teredo has been disabled:
    
  • Type REG_DWORD 0x4
    
• You can re-enable Teredo by running the following command from the Admin command prompt:
  
  • netsh interface Teredo set state type=default
    

Check the TcpIp6 registry path:

• Right-click the Start icon, and then select
  Command Prompt (Admin).
  
• Run the following command from the Admin command prompt:
  
  • reg query HKLM\System\CurrentControlSet\Services\TcpIp6\Parameters
    
  • If the output includes the following line, and the value displayed is not
    0x0, Teredo may have been disabled:
    
  • DisabledComponents REG_DWORD 0x8e
    
• You can re-enable Teredo by running the following command from the Admin command prompt:
  
  • reg add HKLM\System\CurrentControlSet\Services\Tcpip6\Parameters /v DisabledComponents /t REG_DWORD /d 0x0
    

Important: The registry is a database in Windows that contains important information about system hardware, installed programs and settings, and profiles of each of the user accounts on the computer. Windows often reads and updates the information
in the registry.

Normally, software programs make registry changes automatically. You should not make unnecessary changes to the registry. Changing registry files incorrectly can cause Windows to stop working or make Windows report the wrong information.



**Please take a backup of the registry. To take back up, follow the steps mentioned in article:

How to back up and restore the registry in Windows.




Hope it helps.

Teredo is unable to qualigy

Hello,

Thank you for writing to Microsoft Community Forums.

I understand that you are unable to join or host an Xbox Live multiplayer game. If you are getting an error message saying
Teredo is unable to qualify, then your PC is unable to obtain a Teredo IP address. 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.

I suggest you to try few troubleshooting steps to fix this issue, Refer the following article for troubleshooting steps to fix error,
Teredo is unable to qualify.
