Call of Duty Modern Warfare 2: How to Solve the Error Code HUENEME – CONCORD “Networking is Offline”

With a ton of new players jumping into the fray of Modern Warfare 2’s multiplayer beta, many are already experiencing technical issues preventing them from playing the game.

Given the nature of the current state of multiplayer as a ‘beta,’ this isn’t all too surprising. We’ve got plenty of ways around this if you find yourself locked out from joining any online games.

There are a number of potential solutions we will go over in our straightforward ‘How to Fix the Error Code HUENEME – CONCORD’ guide. The resolution will depend on what the root cause of the networking issue is.

How to Fix the Error Code HUENEME  – CONCORD “Networking is Offline” in Modern Warfare 2

Restarting your console and the game

This is obviously the most simplistic and straight-foward option. This would be the first thing we recommend trying before tinkering with network settings. Simply exit the game, restart the console, and try loading up the game again. If this is all that’s required, consider yourself blessed.

Restarting your router

If restarting your console fails to work, the next two options involve trying to restart the router or reinstalling the beta. Simply try restarting your router/modem. As older or refurbished routers/modems will tend to deteriorate in quality and functionality over time – this could be the potential root cause of the issue.

You’ll want to ensure you wait at least 15 seconds before plugging back in the modem, and a couple of minutes before powering back up the router. Having a newer router can also help to reduce latency and lag in-game.

Reinstall the beta

Delete the beta by going to -> ‘Settings’ and then ‘Storage.’ Then, once deleted, reinstall Modern Warfare 2. If playing on a PS5, start the PS5 in safe mode and select the option to “Rebuild Database.”

Check the actual game servers

Of course, none of the proceeding or preceding steps would be much help if the corresponding game server itself is down. Activision’s online support website for Modern Warfare 2 can be found here, and can keep you posted on any issues with server maintenance.

Check and Retry Network Connection

If the error continues to persist after these straightforward adjustments and resets, you need to actually check your network connectivity for any potential issues. Your ISP could be having issues, there could be an issue with the function of your modem or router, or it could simply be a minor technical issue with the current connection.

If everything is all clear, you should try a different network connection to see if it resolves the issue and then revert back once in-game. If you have a VPN, you could try utilizing a connection through a different region or disabling the VPN entirely. This can help you potentially bypass any server errors related to your region or IP.

Contact Activision Support if issues persist

If you’ve tried all of the above to no avail, the last and final step is to cave and contact Activision’s support for Modern Warfare 2 directly. They will hopefully be able to accurately pinpoint the issue (and work through it with you directly) once you inform them of the error code.
