Reading this guide might show you how to fix the login and matchmaking failed errors 0X00040001, 0X00030001, and more in Gray Zone Warfare.

Even though you probably have the game running with the best settings, playing Gray Zone Warfare is a different issue. With so many players logging in to the shooter at once, it’s obvious that you’re going to face issues. But let’s go over why these errors appear and how to fix them.

Troubleshooting the codes

Matchmaking failed: This problem happens whenever you try to matchmake manually. As of writing this guide, there seems to be no definitive fix but the best bet is to try switching to another serverPro-tip, matchmake on a server that’s less populated. The reason is that the servers at launch are fairly unstable. So if you jump into one with fewer players, you could get into a match quickly. However, this could also mean the servers are down, in that case, check Gray Zone Warfare’s X/Twitter account for information regarding the servers.

Login Error: Some players in the community theorize that it Login Error may have to do with the capacity of the servers. When there’s a lot of players playing at once, others may be left in a queue or facing this particular issue. To make matters worse, there isn’t any fix for this problem at the moment. My advice would be to wait and play the game during off-peak hours.

Steam Authorization Failed (0X00010004): Much like the login error, there’s no rhyme or reason why this error appears on Steam. Unfortunately, the only fix that the community has recommended is to restart your computer. If that doesn’t work, you may have to wait for the developers to put out a hotfix for the game. It may be sooner than later because the issues are mounting. 

Gray Zone Warfare plays a lot like Escape for Tarkov. Discover what other games emulate the same immersive playstyle as these extraction shooters.
