How to fix MW3 Hueneme Concord error

This code again?!

The Call of Duty network is no stranger to error codes and laggy performances, especially during its launch periods. One issue, in particular, is the MW3 Hueneme Concord error, which has been plaguing screens since the days of MW2. Fortunately, there are several ways to address the issue.

MW3 Hueneme Concord error solution, troubleshooting

The Hueneme Concord derives from network connection problems, where your system appears offline. Here are a few techniques to fix the problem:

  • Restart the game file
  • Run Modern Warfare 3 as the administrator
  • Restart your router
  • Ensure that the MW3 server is online
  • Repair game files
  • Update MW3 files
  • Change Activision account region

I’ve encountered the Hueneme Concord error in MW3 whenever I’ve left the game on and stepped away. These instances typically log you off after a while, hence the reason for the code notification. A quick restart works just fine to get the system back online. However, the method isn’t bulletproof, so it may mandate a restart for the console/PC or router.

Sometimes, the error isn’t something you can fix on your end, as the Call of Duty network may be down. Check the game’s server status on DownDetector to see if other players have been experiencing problems. If there is a surge in reports, it will likely be the leading cause of the Hueneme Concord error, meaning it could require some waiting. The Call of Duty Updates Twitter/X account is an excellent place to keep track of any fixes or updates.

Considering these updates, you should also ensure that any new patches have been installed for Modern Warfare 3. There are certainly a lot of patches to go around, and it can be hard to miss the latest features. I know this comes at the price of storage, but you can remove unwanted files, like beta versions or modes you don’t play as much.

PC users can adjust other properties for the Hueneme Concord issue by running the game as an administrator. Unfortunately, this device seems to be the most troublesome with the error, so it could take a bit to work correctly. If all else fails, changing regions in your Activision account has been a successful solution for many players.
