“Error Code 4” in Warhammer 40,000: Space Marine 2 is a generic server connection issue. It is not an error with your game files, but rather an issue that prevents your game from maintaining a stable connection to the servers.
đ§ What is Error Code 4
It shows up when the game loses connection to its online services/servers.
Can happen on any platform (Steam/PC, Xbox, PlayStation)
Possible triggers include VPNs, bad internet setup, DNS or firewall issues, device configuration mismatches, or serverâside problems.
đ§ Possible Fixes
These are things people have tried that often help with Error Code 4. Might not all apply depending on your setup.
| Fix | What to Do |
|---|---|
| Turn off VPN / Proxy | If youâre using a VPN, proxy, or any network rerouting tool, disable it. Many reports say this solves Error Code 4. |
| Check/Restart Internet / Router | Turn off your Wi-Fi or disconnect network, wait ~30 seconds, reconnect. Use wired Ethernet if possible (more stable). Reboot router. |
| Use Different DNS Servers | Switching to public DNS like Googleâs (8.8.8.8, 8.8.4.4) has helped some users. |
| Verify Game Files | If on PC / Steam, use the âVerify Integrity of Game Filesâ option in the gameâs control panel to check for corrupted/missing files. |
| Disable Overlays / Extras | Steam overlay, other inâgame overlays, etc., may interfere. Try turning them off and see if it helps. |
| Sync System Time & Time Zone | Some reports say incorrect time settings cause this error. Setting date/time/time zone to automatic or syncing helps. |
| Check Server Status | Sometimes the issue is on Saber Interactiveâs end. Check their support/forum / official server status pages. If the servers are down, there’s nothing you can do other than wait. |
| Reset Network Configuration | On PC, run commands like ipconfig /flushdns, netsh winsock reset, etc., or reset your router to factory settings. |

Adjust Router Settings (Advanced):
If none of the above work, the problem may be related to your router’s port settings. Users have reported success by manually opening the following ports:
- TCP: 27015, 27036
- UDP: 27015, 27031-27036
If you’ve tried all of these solutions and the error persists, it’s best to report the issue directly to the official Focus Entertainment Support Center.
â ď¸ Things to Check / Keep in Mind
If youâre on console, options like changing DNS or running commands are more limited. Focus on router, internet, and server status issues.
If the error started after a patch/update / only recently, it could be a bug introduced in that update. The developers may fix it in a patch.
Make sure your game is fully up to date. Even small fixes can resolve connectivity issues.
If youâre using public Wi-Fi or a restricted network (campus, work, etc.), there might be firewall/NAT restrictions.
