How to fix COD Warzone dev error 6328?

In order to fix Call Of Duty Warzone dev error 6328, you’ll need to try a number of solutions. Learn what you need to do below.

Fix #1: Verify the server status.

Make sure to check if there’s an on-going server outage or maintenance at the moment. To do that, visit the official Activision server status page.

Fix #2: Check for game updates.

If you can’t seem to join a multiplayer match, or if Warzone crashes and shows the error while waiting in the multiplayer lobby, be sure to check for game updates before you restart your computer and launch the game again. This ensures that the next time you try to join a match, the game client has already been updated.

If there’s no updates to be installed at the moment, then simply skip to the next solution.

Fix #3: Install GPU drivers.

Aside from making sure that the game is up-to-date, you also want to check if your graphics card needs the latest drivers. By default, your computer should already be equipped with a special software that comes with your GPU. For example, if you have an NVIDIA graphics, there should already be an NVIDIA GeForce app that should check for Game Ready driver. The same is true if you have an AMD GPU. 

As an alternative, you can open Device Manager and update your display adapters from there.

Fix #4: Power cycle the router.

Another simple way to deal with minor connectivity issues when online gaming is to reboot the router. Refreshing your router is sometimes enough to get rid of network bugs.

Fix #5: Tweak the game display settings.

This a short list of simple changes to your display settings that you can try to fix this dev error 6328:

  • limit FPS to 60
  • Play Warzone on Fullscreen Borderless
  • turn on V-Sync

Fix #6: Run the game on DirectX11.

Warzone can run in both DirectX 11 and 12 but many players have reported that they were able to fix dev errors by opting to use the former. DirectX 11 is more stable than its successor so it’s worth giving a try here.

  1. Open the app.
  2. Load the COD Modern Warfare or COD Warzone game.
  3. Go to Options.
  4. Check Additional Command Line Arguments and enter -d3d11.
  5. Before launching the game again, make sure to restart so these changes take effect.

Fix #7: Terminate other apps.

If other apps or programs are running in the background, it’s possible that one of them is causing a conflict in your game. Try closing all unnecessary apps using Task Manager and see if that works.

Fix #8: Turn off Crossplay.

Crossplay issues are supposed to be gone by now but some players are saying that turning this feature off on their PC helps in fixing this dev error. If you haven’t tried it yet, just open the Warzone Settings menu and disable crossplay from there.

Fix #9: Repair game files.

Game and cache files may become corrupted and lead to problems. To ensure that you have a good set of Warzone game files, try using the Scan and Repair tool of the client.

  1. Open the Blizzard desktop app on your PC.
  2. Click the icon of the game you are trying to repair.
