If you are experiencing the “Request Failed Error (504)” in r2modman, this guide will help you understand the cause and provide solutions to fix it.

Why Does This Error Occur? The 504 status code indicates a gateway timeout, meaning the request sent by r2modman is not receiving a response from the server within the expected time. This can happen due to:

(i). Network connection issues (ii). Firewall or antivirus blocking the request (iii). Server-side problems or downtime (iv). Corrupt cache files in r2modman

Steps to Fix the Error

  1. Check Your Internet Connection Ensure your internet is stable. Restart your router or try switching to a different network.

  2. Disable VPN or Firewall Sometimes, VPNs or firewalls block mod manager requests. Temporarily disable them and check if the issue persists.

  3. Run r2modman as Administrator Right-click on r2modman and select “Run as Administrator” to ensure it has the necessary permissions to make requests.

  4. Verify Server Status If the mod hosting server is down, the issue is temporary. You may need to wait until the server is back online.

  5. Clear Cache Files Open r2modman settings and clear cached files to remove any corrupted data that might be causing the error.
