Should this prove ineffective, proceed to reboot your PC, PlayStation, or Xbox console.

If no apparent issues are found with your game or device, consider restarting your internet connection. Additionally, running a speed test can help in determining whether your internet is causing the problem.

It’s strongly advised to confirm that you have installed the latest patch or ensured that the update download has been fully completed.

If the status indicator displays a green light, it indicates that the servers are operating smoothly, suggesting that the issue may be localized to your end.

Conversely, if there’s no green light, it suggests that the servers are encountering difficulties, and it may be necessary to wait until the developers address the Hueneme Concord error completely.
