  6. Then wait to check if the update’s download failed issue is resolved.

Perform a Cold Restart the of Console/System and Networking Equipment

Warzone error 48 could be a result of a temporary communication glitch between the system/console and Warzone servers. In this scenario, performing a cold restart of the console/system and networking equipment may solve the problem.

  2. Now, unplug these devices from their respective power sources and wait for 5 minutes.

  5. Now launch Warzone and check if its download failed issue is resolved.

Try Another Network

Warzone might show the error code 48 if the ISP is restricting the game’s access to a resource essential for the game’s update. In such a case, trying another network may resolve the download failed issue.

  1. Exit the game and close its related processes in the system’s Task Manager.
  2. Then disconnect the system from the current network (Ethernet or Wi-Fi) and connect to another network (like a mobile phone’s hotspot but keep an eye on the size of the download).
    Enable Hotspot of Your Phone
  3. Now, launch the Warzone game as administrator and check if its download failed issue is resolved.

Disable the System’s Antivirus/Firewall

Warzone might show the download failed error code 48 if the system’s antivirus or firewall is restricting access of the game to an essential update resource. Here, disabling the system’s antivirus/firewall may solve the problem.

Warning: Advanced at your own risk as disabling the PC’s antivirus/firewall may expose the data/system/network to unforeseen threats.

  1. Firstly, exit the game and end processes of associated modules in the Task Manager.
  2. Then, expand the hidden icons of the system’s tray and right-click on the antivirus (e.g., ESET).

If none of the above did the trick, then the partial application of the game’s update might have corrupted the game’s installation and only the tedious task of reinstalling the game (it may take 100+GBs during download) may solve it.

  1. Firstly, backup the essential data/info of the game.
  2. Now open the Battle.net launcher and select the Call of Duty Warzone.
  3. Then, click on the Gear/Settings icon (just beside the Play button) and select Uninstall.
    Uninstall Call of Duty Warzone
  4. Now confirm to uninstall the Warzone and wait till the game is uninstalled.
