Why does the Helldivers 2 request 2 error 0 status 504 happen?

A 504 error in Helldivers 2 can have a few causes. Typically, it has to do with issues on the server side, either because the game is going through maintenance or the servers are just overloaded.

However, at times, the issues are not on the developer's end; network conflicts at home can sometimes block the title from connecting fully, to the point of causing a 504 error. Firewalls, VPNs, and proxies can conflict with the game connecting properly. On top of that, an unstable internet line or a faulty router can trigger the timeout too.

Finally, client-side hiccups like corrupted files, outdated patches, or a broken Steam cache may also cause the issue.

If waiting and restarting don’t fix the 504 error, the next step is checking your network setup.

Flush DNS cache

Open Command Prompt (Admin) > type ipconfig /flushdns > hit Enter > restart your PC.

Reset network settings

Run these in Command Prompt (Admin):

• netsh winsock reset
• netsh int ip reset all
• netsh winhttp reset proxy

Restart again after running them. We also recommend disabling any VPN or proxy since they can interfere with server handshakes and double-checking that Helldivers 2 isn’t being blocked by Windows Firewall or your antivirus.
