   netsh
   
   int teredo
   
   set state disabled
   
   int ipv6

Change the DNS Settings of Your Device

The DNS servers are used to resolve the web addresses related to different online content and if the DNS server of your system/ network is failing to resolve the web server addresses of Forza Horizon, it may fail the connection handshake.

Clean Boot Your PC and Disable/Uninstall the Conflicting Applications

In the Shared Windows environment, in a rare case, some apps may conflict with each other for the system resources and if your system has an application that conflicts with the Forza Horizon, it may force the game into the IPSEC 0x00000000 error. Before proceeding, check if reinstalling the PC’s Xbox app clear out the IPSEC error.

6. Once found, either keep the conflicting application disabled during the system’s boot or uninstall the application (if not essential).

Following applications are reported by the users to cause the IPSEC issue at hand and if any of these applications are present on your system, then either you disable it or uninstall it:

Edit the Firewall Settings of Your Device

The blocking of Forza Horizon’s traffic by the firewall of your system, either unintentionally by the user or by another app, may result in the IPSEC 0x00000000 networking issue. In such a case, editing the Firewall Settings of your device to allow the Forza Horizon traffic may solve the problem.

Warning:

Proceed at your own risk as editing the firewall’s settings of your system may expose your data/system to online threats.

1. Firstly, disable a 3^rd party firewall app (if installed) by right-clicking on its icon in the system tray and select Pause Firewall.

   

2. Now, launch the Forza Horizon and check if it is operating fine.
3. If not and Windows Firewall was enabled after disabling the 3^rd party firewall, disable the Windows Firewall and check if the Forza Horizon issue is resolved.
4. If not, enable the Windows Firewall and click on Windows.
5. Now search for Control Panel and then open Control Panel.

   

6. Then expand the dropdown of View By and select Small Icons.

   

7. Now open the Windows Defender Firewall and in the left pane of the window shown, click on Restore Defaults.

   

8. Then confirm to restore the Windows Defender Firewall to the defaults and afterward, launch the Forza Horizon to check if it is operating normally.

Reinstall the Forza Horizon Game

Forza Horizon’s installation might become corrupt due to a sudden power failure or an essential game file is deleted by another application (like antivirus). This corrupt installation of the Forza Horizon game may cause the IPSEC issue at hand by not fulfilling the network handshake. In this context, reinstalling the Forza Horizon game may solve the problem. Before proceeding, make sure to back up the Forza Horizon’s essential info/data.

1. Right-click on Windows and open Apps & Features.
2. Now expand Forza Horizon and click on Uninstall.

   

3. Then confirm to Uninstall Forza Horizon and follow the prompts to complete the uninstallation of the game.
4. Now restart your PC and upon restart, right-click on Windows and select Run.

   

5. Then navigate to the following path:

   %localappdata%

   

6. Now delete the folders and sub-folders related to Forza Horizon, especially, the following directories:

   \NVIDIA\NvBackend\ApplicationOntology\data\translations\
   
   \NVIDIA\NvBackend\ApplicationOntology\data\wrappers\
   
   \NVIDIA\NvBackend\VisualOPSData\

7. Once deleted, reboot your phone and upon reboot, reinstall the Forza Horizon game and hopefully, it will be clear of the error IPSEC 0x00000000.

If nothing has worked, then check if creating a new Xbox account and using that account to play Forza Horizon sorts out the issue.

If the issue persists, then check if setting up a DMZ (at your own risk) on your router resolves the issue. If it goes through, then check the router for the misconfigured setting creating the issue. We strongly recommend not to permanently use the DMZ on your router due to security concerns. If nothing works out, then you may contact Forza Horizon support to check if your account is under a shadowban.
