If you’re getting Dev Error 841 in Modern Warfare 3, don’t worry. You’re not alone. This is a common error that players have been experiencing during the beta testing phase.

What is Dev Error 841 in Modern Warfare 3?

Dev Error 841 in MW3 is a harmless error that occurs during gameplay. It typically kicks a player out of the active lobby and returns them to the game’s home screen. Fortunately, this error does not result in matchmaking cooldowns or penalties for leaving an ongoing match. However, repeated disconnects may flag your account on the official server.

Dev Error 841 appears to be a server-side error. Since MW3 is currently in the beta phase, the servers may experience heavy load due to the influx of players trying out the game. This heavy load can cause the server to lose connection and disconnect players from the official matchmaking service.

How to Fix It

Since Dev Error 841 is a server-related issue that is beyond your control, there’s nothing you can do to fix it. However, if you find yourself constantly encountering this error during matches, here are some steps to help resolve it:

  • Restart both your internet connection at the router and your console or PC.
  • Wait for your internet connection to stabilize.
  • Start the game again and search for or enter a multiplayer match.

In most cases, following these steps should resolve the Dev Error 841 issue, allowing you to continue playing MW3‘s multiplayer without further interruptions. Remember that as the game is in its beta phase, occasional server-related errors may occur, so patience is key as the developers work to address these issues.
