If you’re having problems playing Warhammer 40,000: Darktide, you’re not the only one. There are several issues plaguing the game, and most of them are server related. Having said that, Error code 4001 is a bit different as its problem is connected to PC Game Pass. Here’s how to fix this issue and continue playing this co-op first-person role-playing shooter.

How to fix Error Code 4001 - Warhammer 40k Darktide

Error code 4001 appears if you’re playing Warhammer 40k: Darktide via PC Game Pass. Everything works fine during the prologue, but after that, the error message appears. There are several things for you to try while you wait for developers to patch things up.

  • Try switching the game host - if you have a “hot join party hub failed” problem, try changing the party leader, so another player is a host for your game. Wait a bit - it’s not rocket science, but the servers may be down because of the large traffic. In that case, all you can do is wait.

Other players have tried all sorts of things, from reinstalling the game to using a VPN (which we don’t recommend). At the end of the day, all you can do is try to avoid server traffic jams. If that doesn’t work, wait for the official Warhammer 40k: Darktide Error code 4001 fix.
