🎮 Game Error Codes What it means & how to fix it

Warhammer 40K Darktide Error Codes

Warhammer 40,000: Darktide's errors are almost all server-connectivity codes from Fatshark's backend. 9999 flags a local network issue on your side, 2001 is the 'non-existent channel' disconnect, and the 4001/4008/3013 family are backend/connection timeouts, often during peak load or maintenance. A VPN frequently interferes, so most fixes are about giving the client a clean route to the servers. Here's what each common error means and the fastest fix.

Error codes

9999 A local network issue is blocking the connection

Cause: Fatshark attributes 9999 to a problem on your side of the connection — an unstable link, a VPN interfering, or a temporary route problem to their servers.

Fix:
  1. Wait a few minutes and retry — many 9999 drops are a temporary local hiccup that clears on its own.
  2. Reset your internet connection and power-cycle your router.
  3. Play without a VPN — Fatshark recommends disabling it, as it can interfere with their servers.
2001 'Non-existent channel' server disconnect

Cause: A server disconnect tied to either connectivity issues or your system not meeting requirements during the session.

Fix:
  1. Restart the game and rejoin — this clears most 2001 disconnects.
  2. Check your internet connection and restart your router.
  3. Verify the game files and update your graphics drivers if it persists.
4008 Client failed to connect to the server in time

Cause: The client couldn't reach the server within the allowed window (a safeguard against continuous standby), usually from server load or a blocked/slow connection.

Fix:
  1. Retry after a short wait — it often connects on a second attempt.
  2. Allow Darktide through your firewall/antivirus and disable any VPN.
  3. Use a wired connection and restart your router before reconnecting.
4001 / 3013 (Backend Error) Darktide's backend couldn't complete your request

Cause: A backend/server-side problem, commonly during peak load, maintenance, or an outage.

Fix:
  1. Check Darktide/Fatshark status channels — if the backend is down, wait for it to recover.
  2. Restart the game and your PC, then log in again.
  3. Reinstall the game only if backend errors persist after the servers are confirmed healthy.

Fixes that work for most Warhammer 40,000: Darktide (PC & Xbox Series X|S) errors

  1. Check the game's server status first (official status page, or the studio's support/X account) — most named connection errors are a maintenance window or outage, and no local fix will help until servers are back.
  2. Restart the game and your PC/console, and power-cycle your router — a fresh connection clears the majority of temporary login and connection errors.
  3. On PC, allow the game and its launcher through your firewall and antivirus, and disable any VPN or proxy — these block the authentication handshake behind many 'can't connect' codes.
  4. Flush your DNS (Command Prompt: ipconfig /flushdns) or switch to a public DNS like 8.8.8.8 / 1.1.1.1 if the game can't reach its servers.
  5. Verify/repair the game files (Steam: Properties -> Installed Files -> Verify; launcher: repair) if the error points at a corrupted install or update.
