How to Fix IPSEC 0x00000000 Error on Forza Horizon 4

Forza Horizon is one of the most famous racing video games and is quite enjoyed by the players. For many users, it is smooth sailing, but some unlucky ones fail to launch the game or join its online mode with IPSEC error 0x00000000.

Forza Horizon 4 IPSEC 0x00000000

The Forza Horizon IPSEC issue can be caused by many different factors but we can identify the following chiefly responsible for the issue:

  • Incorrect Date and Time of the Device/System: The PC’s date/time is used to sync different system states to the game servers and if the date/time of your system is incorrect, Forza Horizon may fail to sync with its servers, resulting in the IPSEC issue.
  • Wrong DNS Settings: DNS servers are used to resolve the domain addresses of the games/websites and if your PC cannot resolve the web addresses of the Forza Horizon, the game may throw the issue at hand.
  • Improper Configuration of Different System Services: There are system services (like IP Helper service) that are essential for the operation of the Forza Horizon and if any of such services or their dependencies are not started or stuck in an error state, you may encounter the error message.
  • Disable Teredo Filter in the Router Settings: The router plays a vital role in Forza Horizon’s communication with its servers and if the Teredo filter is disabled in the router’s setting, then it may cause the Forza Horizon issue.

Before moving on with the solutions, make sure the Xbox/game servers are up and running. Moreover, check if trying any of the following short solutions/workarounds sort out the issue for you:

  1. Update your Windows to the latest built.

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:

  • National Instrument (NI) Suite
  • LabView
  • MultiSim
  • VPN applications
  • VPN adapters in the Device Manager
Uninstall NI Instrument Software

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 3rd party firewall app (if installed) by right-clicking on its icon in the system tray and select Pause Firewall.
    Pause ESET Firewall of Your System
  2. Now, launch the Forza Horizon and check if it is operating fine.
  3. If not and Windows Firewall was enabled after disabling the 3rd 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.
    Open Control Panel
  6. Then expand the dropdown of View By and select Small Icons.
    Open Windows Defender Firewall in the Control Panel
  7. Now open the Windows Defender Firewall and in the left pane of the window shown, click on Restore Defaults.
    Restore the Windows Defender Firewall to the 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.
    Uninstall Forza Horizon from the Apps & Features
  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.
    Open the Run Command Box from the Quick Access Menu
  5. Then navigate to the following path:
    %localappdata%
    Open the Local App Data Folder Through the Run Command Box
  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.
