Fix: Warzone Mobile Matchmaking Lobby Error Code 2004

As per several reports in the last week, it looks like plenty of new errors or issues have recently increased due to the overloaded number of active players at the same time. If we take a quick look at the error message, it says “A matchmaking lobby error has occurred; please retry the operation. Error cause: 10. Error code: 2004.” That indicates there are some connectivity issues with the game servers while matchmaking or getting into the match online.

Luckily, there are some methods mentioned below that should come in handy to resolve such an error. Although the server-side error can only be fixed by the developers and there is nothing to do at your end unless the internet connectivity issue is troubling you. Sometimes an outdated game version, issues with the corrupted or missing game files, using VPN or Proxy servers, slow internet, not downloading required resources, and more can be a reason.

1. Restart the Mobile

First of all, you should try restarting the mobile device to ensure there is no temporary system glitch present on your handset that can trouble in playing the Warzone Mobile game.

For Android:

  • Just close all running applications including the game and then long-press the Power key to get the Power Menu.
  • Now, tap on Restart and wait for the device to boot again.

For iPhone:

  • If you’re using an iPhone 6, 7, 8, or SE (2nd or 3rd generation):
    • Press and hold the side button until the power-off slider appears.
    • Drag the slider, then wait 30 seconds for your device to turn off. If your device is frozen or unresponsive, force restarts your device.
    • To turn your device back on, press and hold the side button until you see the Apple logo.
  • If you’re using an iPhone X, 11, 12, 13, or later:
    • Press and hold the Volume button + the Side button until the power-off slider appears.
    • Drag the slider, then wait 30 seconds for your device to turn off. If your device is frozen or unresponsive, force restarts your device.
    • To turn your device back on, press and hold the side button (on the right side of your iPhone) until you see the Apple logo.
  • If you’re using an iPhone SE (1st generation), 5, or earlier:
    • Press and hold the top button until the power-off slider appears.
    • Drag the slider, then wait 30 seconds for your device to turn off. If your device is frozen or unresponsive, force restarts your device.
    • To turn your device back on, press and hold the top button until you see the Apple logo.

2. Update COD Warzone Mobile

Sometimes issues with the outdated game version on the handset might also occur several conflicts while launching the COD: Warzone Mobile game. It’s better to check for the game update and install it whenever available. To do that:

For Android:

  • Open the Google Play Store app > Tap on the hamburger menu icon.
  • Now, tap on My Apps & games > Then check for the Warzone Mobile game update is showing on the list of available updates or not.
  • If so, just tap on the Update button next to the app and wait for it to install.
  • Once done, make sure to open the Warzone Mobile game, and check for the issue. [You can also restart your handset to refresh the system and app data]

For iPhone:

  • Open the Apple App Store on your iPhone.
  • Next, tap on the Profile Picture icon from the top-right corner.
  • Scroll down a bit to see which apps are available for update.
  • Check if the Warzone Mobile game update is on the list or not.
  • If the Update option is available for the game, just proceed.
  • Wait for the installation process to complete.
  • Once done, make sure to launch the Warzone Mobile game.

3. Ensure Downloading All Required Resources

It’s highly recommended to download all the required or pending resources that need to be installed completely before playing the game or accessing content. Mostly Warzone Mobile players avoid additional resources download and it can trouble a lot. Always keep your game up-to-date.

4. Check for the Internet Connection

You should always check out the internet connection status at your end because issues with the network stability or speed can occur in plenty of conflicts while launching an online multiplayer video game or even connecting to the server. During the initial loading, the game files always try to connect to the servers for multiplayer support and access user profile, in-app purchases, rewards, matchmaking with other players, etc. In that case, the internet issue can play a major role, and contacting the service provider can help to fix it.

5. Clear Game Cache and Data

If you’re trying to play COD Warzone Mobile on your Android device then try clearing the app cache data and the storage data from the settings menu of the game application to refresh glitches. Sometimes outdated or corrupted app cache data can also cause several issues with the lobby matchmaking error whatsoever.

Note: There is no option to do this on iPhone. Only a simple restart will do the job.

  • Go to the device Settings menu > Head over to Apps & Notifications.
  • Now, tap on See All Apps > Head over to Warzone Mobile under the App info section.
  • Tap on Warzone Mobile to open the app info page > Tap on Storage & Cache.
  • Next, tap on Clear Cache > Once done, tap on Storage & Cache.
  • Then tap on Clear Storage > Launch the game to check for the issue.

6. Don’t Use VPN


It’s highly recommended not to use a VPN service on your mobile device or the router to avoid ping latency issues. When it comes to the server connectivity issue or the matchmaking error, disable VPN temporarily to check for the issue again.

7. Try Enabling Two-Factor Authentication on Activision Account

Some of the players have claimed that enabling the 2FA on the Activision account did the trick to avoid startup issues or server connectivity errors. You can also try it out.

  • Go to the Activision website > Click on the ‘Login’ option.
  • Log in to your valid Activision account > Go to your profile.
  • Select ‘Privacy & Security’ > Click on the ‘Enable two-factor authentication’ option.
  • Now, make sure to follow the on-screen instruction to enable 2FA.
  • Once done, open Warzone Mobile on your handset.
  • Head over to Warzone Settings > Go to Account > Tap on Log out > Hit Continue.
  • Restart Warzone Mobile > Log in to the account.
  • Finally, enter your 2FA code, and you’re good to go.

8. Reinstall COD Warzone Mobile

If none of the methods worked for you then make sure to uninstall and reinstall the Call of Duty Warzone Mobile game on your mobile. It’ll eventually delete all the saved game application data and refresh its data which might fix the lobby matchmaking error. To do so:

For Android:

  • Now, select Remove App from the pop-up menu > Tap on Delete App.
