Can you please check that the port exposed by the app is the same used in Settings->Networking->Public network?

Hi! A 502 Bad Gateway usually means the Railway proxy can't talk to your application. Since it worked initially, here are the quickest things to check and fix:

Check the Port & Host Bindings

Make sure your app listens on host 0.0.0.0 (not localhost or 127.0.0.1).

  * Verify that the port your code listens on matches the PORT environment variable or the Target Port set in your Railway service settings.

Inspect the Application Logs

Go to your Railway dashboard, click on the service, and look at the Logs tab.

  * Look for any crash messages, unhandled exceptions, or memory-limit exits that happened right after deployment.

Database or API Connection Issues

If your app tries to connect to a database or external API on startup and times out, it might cause the server to hang or crash, triggering a 502.

Welcome!
