Try performing a quick fix by resetting your router if you experience this error. Temporary issues with your internet connection can result in this error, and resetting your router can help resolve such issues.

To do this, unplug your router from the power outlet, wait for a minute or two, and then plug it back in. This restarts the router and refreshes your internet connection, potentially fixing the error.

After the router has rebooted, try playing the game again to see if the error is resolved.

#3) Check for COD MWII Updates

It’s crucial to manually verify that the game is up-to-date to avoid any pending game updates that may cause multiple game issues or glitches. Follow the steps below to verify the game update.

9. Restart your PC.

If you’re a console gamer, restart your console and router, then wait a couple of minutes before turning them back on.

#5) Change DNS Settings

If you are still experiencing the Hueneme Concord: Networking is Offline error, it may be worth considering changing your DNS settings on your router, console, or PC. To do this, log in to your router and navigate to the setup page. Keep all existing settings the same, but change your primary and secondary DNS to any of the following options:


Alternatively, you can install the Cloudflare app, which allows you to toggle OpenDNS on or off. Simply visit and download the app for Windows. Once installed, turn it on and attempt to play Modern Warfare 2 or Warzone 2. This should resolve the issue in most cases, and you should no longer see the Hueneme Concord: Networking is Offline Error.

#6) Turn off Teredo

If you’re encountering issues with your game, disabling Teredo might help. Teredo is an IPv6 tunneling system built into Windows, and some users have reported success with disabling it. Here are the steps:

1. Press the Windows key and R key simultaneously to open the Run dialog box.

2. Type “cmd” and press CTRL+SHIFT+ENTER to open the command prompt as an administrator.

3. Type “netsh interface teredo set state disabled” and press Enter.

4. To confirm that Teredo has been disabled, type “netsh interface teredo show state” and press Enter.

5. Launch your game and see if the issue has been resolved.

Note that Teredo is used by many games on the Xbox app, so if you play any of these games, you may want to save the disable command somewhere so that you can re-enable it in the future. To do so, simply replace “disabled” with “enabled” in the command.

#7) Use a VPN

Playing on a different server from the one where the game is installed may be the source of connection problems and is usually the reason for Hueneme Concord MW2. That’s why you should consider using a VPN to connect to the dedicated server located in a specific country.

To enjoy an uninterrupted game with your squad use a premium VPN that will not affect your connection issues or the FPS and Ping of the game. We highly recommend ExpressVPN which runs servers in 94 countries and it offers fast connections.

In conclusion, I genuinely hope that the troubleshooting steps mentioned above will help you resolve the connection issues you are experiencing in Hueneme Concord while playing MW2. However, if none of these steps work for you, it’s recommended to contact Activision Support for further assistance or wait for new updates to be released by the developers.
