Many users have reported seeing the Warzone Diver error code when launching the game. The issue is said to occur on PC or PS4 mostly. The problem is reported after or during a game update. Warzone can display the Diver error code for many reasons, but the main ones are:
- Network Issues: If an ISP is preventing traffic required by Warzone, or if a misconfiguration of the router is restricting Warzone’s access to an essential online source, then Warzone may display a Diver error.
- Interference from the System’s Security Application: Interference from the system’s security products blocking Warzone’s access to an essential online resource can cause the Warzone Diver error.
- Corruption of Essential System Files: You may encounter the Warzone Diver error code if the critical system files are corrupted (due to a sudden power failure, for example). This may restrict Warzone’s access to a resource vital to its operation, resulting in a Diver error.
- Corrupt Installation of Modern Warfare: Warzone may display a Diver error code if its installation is corrupted. It may be due to the deletion of game files and false positives from security applications.
Restart the game or reboot your system/console and router
A temporary communication failure can cause the Diver error code in Warzone. The game restarting system and router (which will also update the system’s IP address) can resolve the issue. But before diving into technical solutions, make sure you have enough space on your Warzone installation disk to download and install the game.
- First, close the in-game/launcher and right-click Windows.
- Now select Task Manager and end all Warzone/Modern Warfare processes.
- Open the system task manager through the shortcut menu.
- Then launch Warzone and check if it works fine.
- If not, close the game and power down the system.
- Now unplug the system’s power cable from its source and pull down the router.
- Then unplug the router’s power cable from its inception and wait for 5 minutes.
- Now plug back the power cables to the appropriate power supply and power on the router.
- Once the router is powered on, power it to a system and launch Warzone to check if it has a Diver error code.
Update your Warzone game to the latest build
Warzone may not work if the game is not updated to the latest build, which may result in incompatibilities with other OS modules. Updating the Warzone game to the newest build can fix the problem.
- Exit the Warzone game and be sure to end Warzone-related processes in Task Manager.
- Now open the Battle.net launcher and select Warzone.
- Then expand its Options and click on Check for Updates.
- Wait until the update is applied (if any), then check if the Diver error code is cleared.
If not, check if the game allows shaders to reinstall (when the error message is open) to solve the problem.
Change Warzone Regional Server
The Warzone Diver error may result from a glitch in the Modern Warfare regional server, and selecting a different region may resolve the Warzone Diver error.
- Open Battle.net launcher and select Warzone COD.
- Now click on the globe (near the Play button), and in the mini-menu, select a different region (for example, if you are in America, select Europe or vice versa).
- Then click on Play and if the game asks to update, let it update.
After that, check if Warzone is running without Diver errors when the game starts.
Try a different network or network type
Warzone may display a Diver error code if the network restricts the game from accessing a resource that Warzone requires. In addition, a problem with the type of network connection, such as a defective Wi-Fi card or interference with wireless signals from other electronic equipment, may cause a mistake. You can fix the Diver error using a different network or network type.
- First, exit the Warzone game and kill all related tasks in the task manager.
- Now, connect the system via VPN (if not, you can install a VPN) and launch Warzone.
- If the game is trying to update, let it update, and then check if Warzone is working correctly.
- If not, check if you are using a different network type (e.g., when using a Wi-Fi connection, try an Ethernet cable or vice versa) to solve the problem.
- If the problem persists, exit Warzone and end related tasks in Task Manager.
- Now, disconnect the system from the current network and also connect to another network (like the phone’s hotspot).
- Then start Warzone and if it tries to update, let it update.
- After that, launch Warzone and check if the Diver error code is reset.
Perform an SFC scan of the system
The Diver error code in Warzone is if the core system files are corrupted, which can make resources or directories inaccessible to Warzone. In this context, performing an SFC scan of the system can resolve the Warzone error in question.
Exit the Warzone game and end-related processes in the task manager.
Now, perform an SFC scan of the system (be sure to run the command prompt as an administrator). This may take some time, so try when the system can be freed up for a while.
Once the scan is complete, launch Warzone and check for the Diver error.
Disable the system security app
Warzone may not work or update with a Diver error code if system security software interferes with the game and blocks it from accessing important online sources and local system directories. In this case, disabling the system security product (such as ESET) may solve the problem. Remove any Warzone exceptions in your antivirus/firewall settings before proceeding.
Warning: Proceed at your own risk, as disabling or changing the security application settings may expose the system and data to threats.
- First, exit the Warzone game and close its launcher. Don’t forget to end Warzone-related processes in the system task manager.
- Then expand the hidden icons in the system’s tray and right-click on the security software.
- Now select Pause Projection, and if the UAC prompt is displayed, click on Yes.
- Then confirm disable security and again, right-click on the security product in the remote system tray icons.
- Now select Pause Firewall and then confirm to disable the system security application.
- Then open Battle.net and launch Warzone to see if the Diver error is resolved. You can exclude the Warzone installation directory in the system security app settings.
- If not, repeat step 1 and then disable Windows Defender.
- Now launch Warzone and check if it works fine.
If your security product or system firewall is already disabled, check if enabling it solves the issue with Warzone.
Reset router to factory settings
COD Warzone may display a Diver error code if the router is misconfigured or the router firmware is corrupted. In this context, resetting the router to factory defaults can resolve the Warzone error. After a factory reset, you need to write down the information to set up your router. While the reset process may vary slightly between brands/models, the general guidelines are as follows:
- First, locate the physical reset button on the router, usually on the bottom or behind the router. In some routers, the power button also works as a reset button if you hold it down for a specific time.
- Once the reset button is found, press/hold the reset button on a pointy object (like a paperclip) and wait for 30 seconds.
- Now release is in the reset button and wait until the router turns on.
- Then configure the router (according to the ISP’s instructions) and check if the Warzone Diver error code is cleared.
- If the problem persists, check if the NAT type of the system/console has changed to solve the Warzone problem.
If that doesn’t work, you can set up a DMZ (strictly not recommended) for the system or console IP address to resolve the Warzone Diver error.
Delete files in the Warzone installation directory
- Open Battle.net launcher and select Warzone.
- Now expand Options and click on Show in Explorer.
- Then head to Data, usually the following path: C: Program Files (x86)Call of Duty Modern WarfareDatadata.
- Now delete all files with IDX extension up to 1KB in size.
- Then open the Battle.net launcher and select Warzone.
- Now click on the gear and select Scan and Repair.
- Then wait until the scanning process is complete and start Warzone to check if it works fine.
If not, steer to the Warzone installation directory and open Data.
- Now delete files (not folders) less than 2MB in size and Scan and Repair the Warzone in the Battle.net launcher to check if Warzone has a Diver error.
- If the problem persists, delete all the files (not folders) in the installation directory except ModernWarfare and ModernWarfare Launcher.
- Now run Scan and Repair Warzone in the Battle.net client.
- After that, launch Warzone and check if there is a Diver error.
- If the problem still exists, check if installing (or reinstalling) Modern Warfare Pack 1, 2, and 3 reset the Diver error.
