How to Fix Error Code 38 in Warzone

Most of these problems are best solved with... patience

I feel like I was just writing about this game! Once again, we’re here at Prima to take a look at the world’s most stable videogame, Call of Duty: Warzone. Some players appear to be running into “Error Code 38” messages, which seem to pop up every so often. After looking into possible fixes to this one, it seems like there is a pretty universal cause and solution. About time.

Apparently, Error Code 38 is tied to a missing software update for Call of Duty: Modern Warfare. Despite multiple games following it, Warzone still boots up using Modern Warfare’s client or what have you. So that means if you want to play Warzone, you also have to have Modern Warfare installed on your system or computer.

Troubleshooting Tips for Call of Duty: Modern Warfare and Warzone Error Code 38

If there’s an update to Modern Warfare, it seems like it doesn’t also apply to Warzone’s launcher. So that means if you have automatic updates turned off, and you haven’t checked in on Modern Warfare in a while, you may have missed an update. This seems to be the major cause of Error Code 38.

If you already have everything up to date, there are a couple things you can try, as it seems like something between you and the Warzone servers isn’t landing where it should. Shutting down and power cycling whatever platform you’re using should be the next step, making sure it’s shut all the way down for around 30 seconds before booting it back up.

And if that doesn’t work, you should make sure you’re hard-wired to the internet via an ethernet cable, then reboot your modem.

If you’ve done all of that and are still hitting Error Code 38, you’ve exhausted all of the user-side options you have available. The next step has to be getting a hold of Activision Support and getting a ticket submitted for further assistance (hopefully).
