How to Fix Modern Warfare Multiplayer Not Working on PC/PS4/Xbox

There are 4 applicable fixes to the Call of Duty Modern Warfare not working issue. You can try them in order or choose the one according to your console.

# 1. Launch the Game from Its Dedicated Launcher (PC/Consoles)

As it’s well known, Activision decided to merge Modern Warfare Multiplayer and Warzone into one game launcher, named Call of Duty Cold War. This has brought the ongoing problem with the two games.

If you are expiring the MW Multiplayer not working issue, we recommend you run the game from its dedicated launcher instead of from the Cold War launcher. This solution is confirmed to work on both PC and consoles.

For PC: Just double-click the Call of Duty: Modern Warfare executable file to directly launch the game.

For Consoles: Just use the dedicated list of games to launch COD Modern Warfare and not from the Cold War interface.

# 2. Clear the Cache of Your Console

Another common reason for the Call of Duty Modern Warfare Multiplayer not working error is the corrupted cache data. In this case, you can try clearing the cache files on your PC or console to fix the issue.
