How to fix Darktide error code 9999?

Darktide is one of the latest games from Fatshark’s stable. While the game itself is rather good, it hasn’t seen a great public response due to all the bugs and glitches that players have been facing. While some bugs and glitches are inevitable, seeing them frequently can really drown out any enjoyment you get out of the game.

In this article, we’re talking about Darktide error code 9999, its causes and what you can do to fix the problem.


What causes this error code?

The error code is generally triggered by connectivity issues between the game and the multiplayer servers. This can be caused by a number of reasons:

  • Internet connectivity issues.
  • Darktide servers might be down.
  • Missing or corrupt game files.
  • Firewall or antivirus blocking the game’s connection.

How to fix this?

Here are nine fixes you can try out.

Restart your router

Restarting your router can help eliminate any unseen network or connectivity issues you may face. You have to turn off your router, wait a bit, and then turn it back on again. 


Restart your game

One of the easiest ways to fix the problem is to restart the game. Restarting games and programs often resolves temporary bugs that can cause crashes or connectivity issues. Once the game is stopped completely (you can verify this using the Task Manager), relaunch it using the Steam launcher, and it should work just fine. 


Check for server outages

Another thing you should keep an eye out for is any outage caused on the game’s end. Darktide has a dedicated Twitter account for this as well. So if you feel like the error is being caused by the server’s end, check the aforementioned Twitter profile to see if that’s the case. 


Disable VPN

If you’re using a VPN while gaming, some games can experience issues due to geo-restricted content policies. Disable it and try rerunning the game if you’re on a VPN. It should work just fine. The same goes for any firewalls you might have as well. 


Check Firewall

Sometimes the Windows Firewall can get in the way of programs trying to access the internet, which can very well be the case here. Try temporarily disabling your firewall to see if Darktide starts working properly.

Change NAT type

If your router has a NAT type 3, otherwise called strict, you will run into problems with a game, as strict NAT types often block internet traffic to non-essential programs. If you have admin access to your network, try changing the NAT type to see if that resolves your error.

Verify Game Files

Corrupted game files can often lead to issues like this, not just in Darktide but other games. Luckily, Steam has a built-in feature that verifies your game files and reinstalls any files that might be damaged. Follow these steps.

Step 1: Head over to your Steam Library, right-click on Darktide and select Properties.

Now try relaunching the game. 


Reinstall

If checking the game files didn’t work out, your best bet is to delete the game from Steam and reinstall it from scratch. Ensure to overwrite your game save with the new installation, as corrupt saved files can also cause this issue. 


Wait it out

If nothing resolves the problem, the error is most likely game or server related. In such cases, your best bet is to wait the issue out as the developers usually will either issue a patch to fix the issue in-game or perform maintenance on the multiplayer servers to get the game running.
