How to Fix Dev Error 6144 in CoD MW2

The best way to fix developer error 6144 for this game is to restart the game. This is not an official fix, but since you get it for the game’s multiplayer mode, these are all workarounds you can try to solve:

• Restart the game: Start with the simplest fix that also works best. When you get this error, the game will only give you an Exit button. Click here. Now, when you return to the main screen, instead of starting a new match, close the game. Now run it again and then try to play any multiplayer match and you shouldn’t get this error.
• Play on a wired connection: If you can play the game on a wired connection, select it instead of a wireless connection. A wired connection is more stable and reduces the chance of this error occurring.
• Upgrade Your Internet: There is a good chance that your Internet is working but not providing the best performance. You can fix this by simply refreshing the connection. If you are playing wirelessly, please restart your router. And for a wired connection, disconnect the Ethernet cable from your system and wait 10 to 30 seconds. Then reconnect the cable and try to launch the game.

If none of the above fixes work, then you should wait for the game to update. Once the developers fix this issue and release a patch for it, you shouldn’t get this error.
