How to fix the Hueneme Concord error in MW3

Occasionally, when you fire up Call of Duty Modern Warfare 3 for an intense multiplayer session, Warzone chaos, or a classic Zombie hunt, you may encounter a frustrating error that halts your gameplay entirely.

The Hueneme Concord error has recently surfaced, reminiscent of its counterpart, Hueneme Negev, which plagued both MW2 and MW3. Although it’s unlikely that Activision intended to carry over the same error codes to MW3, it has resurfaced nonetheless. Here’s what’s causing the Hueneme Concord error in MW3 and some potential fixes you can try.

What’s causing the Hueneme Concord error in MW3?

For MW3 players, the Hueneme Concord error typically occurs when attempting to log into online services after launching the game. Often, this error is linked to connectivity issues with Activision’s servers, which are beyond your control.

However, there are instances where the issue may be on your end. Whether due to a weak internet connection, a firewall blockade (on PC), or an improper game launch, there are a few troubleshooting steps you can take to address the problem.

Fixes for the Hueneme Concord error in MW3

Check MW3’s server status

Begin by checking the official MW3 server status to determine if other players are experiencing the same issue. If the status indicates any problems, it suggests an issue on Activision’s end, requiring you to wait until the servers are operational again.

Restart MW3 and your internet connection

Start by restarting MW3, as launching issues may have occurred during the game’s startup. Often, this simple action resolves the problem. If you continue to encounter the Hueneme Concord error, attempt to reboot your internet connection by powering off your modem, waiting 30 seconds, then powering it back on and allowing a few minutes for reconnection.

Restart your PC or console

Restarting your system complements the above fix. Streamline the process by closing CoD, then powering off your PC or console. After waiting 30 seconds, power it on and launch MW3 once it’s ready.

Repair your game files (PC only)

If the Hueneme Concord error persists, consider repairing your MW3 game files. This can only be done on PC via or Steam.

  • For, navigate to the Games tab, select CoD, click the cogwheel icon next to Play, then choose Scan and Repair.
  • For Steam, access your Steam Library, select CoD, right-click, and choose Properties. Under Installed Files, select Verify integrity of game files, then wait for the process to complete.

Submit a ticket to Activision

If you’ve exhausted all other options, consider submitting a support ticket to Activision for further investigation. Visit the MW3 support page, follow the provided troubleshooting steps, and report the issue once all steps have been attempted.

Expect a delay as Activision receives and investigates your report, but remain hopeful that the Hueneme Concord error won’t keep you sidelined for long.
