After the launch of Pacific Update in Call Of Duty Modern Warfare, the multiplayer game mode stopped working for many players. It happened across consoles, from Xbox PlayStation to PC.


Many users experienced a drop in the quality of the gameplay too. The problem seems to be the missing data pack. Until Raven Software, developers of Call of Duty, fix the issue, we have figured out some solutions for the bug.

COD Modern Warfare Multiplayer Not Working

Reasons Behind Modern Warfare Multiplayer Not Working:

You should know the reason before you try to fix the problem. Here are all the reasons why your game might not be working rightly.

  • Inappropriate licensing: Licensing issue occurs for only Playstation users. Restoring your license on your console can fix the problem. Doing this will let your device know that you have a claim for the game.
  • Multiplayer Package missing: Another prominent reason is the missing Multiplayer Package. It is for Xbox new series & PlayStation 5 users. You need to install the missing files for the Multiplayer functionality to work.
  • Using cold war interface: If you’re launching Call of Duty through the cold war launcher, that might be causing the problem. Launch the game directly, instead of the cold war.
  • Cache files corrupted: Corrupted cache files causes problems in many games and programs. These corrupted files can manipulate your system into believing that there is no multiplayer function.

These were the possible reasons for disabling your multiplayer mode in the game.

Fixing Call of Duty Modern Warfare Multiplayer Not Working Issue

Now let’s look at the possible fixes for the reasons stated before:

Directly launching Call of Duty Modern Warfare

First & foremost, launch the game directly from the dedicated launcher and not the Cold War launcher. The Cold War launcher has been known for disabling the multiplayer feature ever since it got introduced.

It works for all the users, Xbox, PlayStation & PC. You have to click directly on the game and start playing. Avoid using the Cold war interface.

Cleaning Cache Files

Clearing cache files work when nothing works. You might be using different consoles, so we have listed down how to clean the game cache files for every device.

  1. PlayStation 5
  2. Xbox Series X & S
  3. PlayStation 4
  4. Xbox One
  5. Steam
  • Clearing Cached data on PlayStation 5

Firstly, you have to press the power button for a while (till you hear a beep sound) and then wait for the light to shut down completely. Make sure you are pressing the power button for a long time. Not doing so will make your console switch to rest mode. 


After the blinking lights are off, you have to remove the power cord from the PlayStation 5. Wait for 2-3 minutes or more after removing the cable as the data gets cleared in the meantime. 

Plug the cord back and boot up your console. You’re good to go. Cache files get deleted, and this might fix your multiplayer issue.

  • Clearing Cached data on PlayStation 4

The process is somewhat similar to PlayStation 5. Press the power button for a long time. Again, pressing it for a short period will start the hibernation mode in the console. 

Wait for the blinking lights to turn off. Then, remove the power cable from the console. Keep it unplugged for 1-2 minutes. After that, plug the wire in and start your PlayStation. 


The cache files will get deleted from your console and hopefully solves the multiplayer issue.

  • Clearing cached data on Xbox Series X & S

Unlike the PlayStation process, in Xbox series X & S, you can clear the cached files internally.

When you are on the home screen, press the Xbox logo button on your controller. Navigate through Profile & System > Settings > All Settings. In the All Settings, search for Device & Connections, select Blu-Ray. Move to persistent storage > clear persistent storage. You have successfully cleared the cache files, and now you have to restart your console.

  • Clearing Cached data on Xbox One

The process is relatively similar to PlayStation. Make sure the device is not in hibernation/power-saving mode. Again, press the power button until the light gets off. Remove the power cord from the console and wait for the cached data to get cleared.


Plug the cord back in and start your Xbox. Check if the multiplayer issue persists.

  • Clearing Cached data on Steam
