Fortunately, here we’ve shared with you some potential workarounds that might come in handy. Make sure to follow all troubleshooting methods until the error or bug has been addressed. Though you can wait for the game developers to investigate the issue further, you can try fixing the issue at your end. So, without wasting any more time, let’s jump into it.
1. Check for Activision Online Services
First of all, you can check out the Activision Online Services by following the steps below to ensure there is no downtime or outage with the server. Conflicts with the server may trigger multiple issues.

- Click on the drop-down menu and select Call of Duty: Modern Warfare III.
- If you’re seeing All Platforms ONLINE then you’re good to go.
- You can also click on the Refresh link to manually refresh the page.
However, if you’re seeing server issues then wait for a couple of hours to check for the same. In case, the services are running fine then head over to the next method.
2. Check Your Network Connectivity
Sometimes issues with the network connectivity at your end may also cause several conflicts with the game launching or connecting to the game servers in the multiplayer mode. If your network connection has lower speed or instability then make sure to change the wired network to wireless or vice versa. You can also try using the mobile data hotspot to check if the specific issue is appearing or not.
3. Click on ‘Yes’ to Proceed
You can also click on ‘Yes’ to proceed further without worrying about data loss. Several reports confirm that even after accepting the prompt, there will be no actual data loss.
