Encountering a backend error while signing into Warhammer 40,000: Darktide can be incredibly frustrating, especially when all you want to do is dive into intense co-op action. These sign-in issues have affected many players and are often tied to server overloads, network settings, or configuration hiccups on the client side. Thankfully, several workarounds and fixes have proven useful in resolving these backend issues.
Understanding the Backend Error in Darktide
The backend error typically appears upon launching the game or attempting to sign in. It often reads something like: “Backend Error: Sign-in failed. Please try again later.” This issue may stem from either server-side problems on Fatshark’s end or local issues such as corrupted files or firewall restrictions.

Steps to Fix the Backend Error in Darktide
If you’re stuck with this annoying error, follow these tried-and-tested methods to get back into the hive city and resume purging heretics.
-
Check Server Status
Before diving into deeper troubleshooting, visit Fatshark’s official forums or DownDetector to confirm whether the servers are down. Login issues during peak hours are often linked to temporary outages or maintenance. -
Restart the Game and Steam
Close both Darktide and the Steam client, and then restart them. This simple step can sometimes bypass minor client-server sync errors causing the backend issue. -
Run the Game as Administrator
Right-click on your Darktide shortcut or executable and choose “Run as Administrator”. Sometimes, permissions can interfere with proper online connectivity. -
Disable Any VPNs or Proxy Servers
Fatshark’s login servers might be sensitive to masked IP addresses. If you use a VPN, try turning it off temporarily and attempt to sign in again. -
Flush DNS and Reset Winsock
Network cache corruption can cause connectivity errors. Open Command Prompt (as admin) and enter the following commands one at a time:ipconfig /flushdns
netsh winsock reset
After entering the commands, restart your computer and try launching the game again.
-
Verify Game Files via Steam
Sometimes, corrupted or missing files can prevent successful logins. Open your Steam Library, right-click Darktide, select Properties, then go to Local Files > Verify Integrity of Game Files. This can detect and fix broken files. -
Temporarily Disable Antivirus or Firewall
Overprotective antivirus programs or firewalls can block Darktide from accessing servers. Try temporarily disabling your antivirus or adding exceptions for the game and Steam.

When All Else Fails: Wait It Out
If all else fails, especially during new updates or weekends, the issue is likely on Fatshark’s end. In such cases, your best option is to wait. Fatshark typically resolves backend issues within a few hours.
