Dear Railway Support Team,

I'm trying to deploy a Node.js/Express application to the Railway platform but consistently encounter 502 Bad Gateway errors. The server logs show that the application starts successfully and is running normally, but all HTTP requests return 502 errors.

Project Information:

Solutions I've Attempted:

  1. Verified Server Starts Correctly

    • Logs show successful MongoDB connection

    • Server running on designated port (5000)

    • All initialization steps completed successfully

  2. Optimized Server Configuration

    • Added CORS configuration

    • Added health check endpoint (/health)

    • Modified static file serving

    • Refined route handling

  3. Tried Railway-Specific Fixes

    • Created a Procfile

    • Added engines field in package.json

    • Used http.createServer to explicitly create server

    • Specified listening on all network interfaces (0.0.0.0)

  4. Simplified the Application

    • Reduced server to bare minimum functionality (10 lines of code)

    • Removed all database connections and complex features

    • Retained only a simple text-responding route

Even with the most simplified configuration, the application still returns 502 errors, suggesting the issue may not be with my code but with the Railway platform configuration.

Requesting Assistance:

  1. Are there any platform-specific configuration requirements I might have missed?

  2. Are there any logs or debugging tools that could help diagnose this 502 error?

  3. Could you examine my project and provide specific recommendations?

Thank you for your help!
