Causes of the Error Code 4 on Call of Duty: Warzone

Why does the Xbox One version of Call of Duty: Warzone show error code 4? The error code was first seen almost two years ago, and even though the developer, Infinity Ward, has released several updates to fix the problem, it still exists.

Most of the time, this happens when the connection between the game and the server breaks. The error could have been caused by a slow Internet connection, server maintenance, or the server being too full.

Either a PC or a console can have this problem. The easiest solution is to restart the internet, but this might not work if your internet connection is slow or if you have used port forwarding or changed your DNS address.

This can also be caused by a bad Internet connection, a broken hard drive, or other things. If you get this error on your Xbox One, make sure the connection is working properly. The Microsoft store could also be to blame for a Warzone error code 4.

Most likely, your game can’t connect to the Microsoft Store, so you can’t get updates. But the problem is easy to fix: just turn off and back on your console. If your connection is still shaky, Microsoft may need a little time to fix the problem.
