This error will kick you out of your current match and send you back to the main menu. While frustrating, it’s not a serious issue and doesn’t impact your account or game progress. Here’s what you need to know about Dev Error 841 and how to potentially fix it.

What is Dev Error 841 in MW3?

Dev Error 841 is a server-side error that appears during multiplayer matches. It is not caused by your internet connection or your hardware, and it doesn’t mean your account is in trouble. The error is likely a result of temporary server issues, and the developers are working to fix it.

How to Fix Dev Error 841 in MW3

While there’s no guaranteed fix for Dev Error 841, there are a few things you can try to potentially resolve the issue:

1. Restart the Game: The simplest solution is to close the game completely and restart it. This can clear any temporary glitches or bugs that might be causing the error.

2. Reset Your Network: A network reset can sometimes help resolve connection issues that might be contributing to the error.

• On PC:
• Open Settings (Windows + I).
• Go to Network & Internet > Advanced network settings.
• Click Network reset under More settings.
• Click Reset now.

5. Reinstall the Game: If none of the above solutions work, try reinstalling the game. This can remove any corrupted or missing files that might be causing the error.
