That Railway page means the edge reached your deployment, but your app did not answer on the port Railway is routing to. The quickest checks: 1. In your app, listen on `process.env.PORT` (or your framework's equivalent) and bind to `0.0.0.0`, not `localhost` or a hard-coded port. 2. 2\. In Railway -> service -> Networking/Public Networking, make sure the public URL is mapped to the same port the app actually listens on. If you changed ports recently, remove/recreate the public domain mapping or update the target port. 3. 3\. Open the latest deployment logs and look for either "listening on ..." or a crash after startup. If the app exits after binding, Railway can still show this generic "failed to respond" page. 4. 4\. If this is Docker, make sure the container starts the web server process and does not only build assets. `EXPOSE` is not enough by itself; the running process still needs to bind to `$PORT`. If you share the framework/language and the log line showing which port it is listening on, the exact fix should be straightforward.

Make sure the port your application is listening to is the same port your URL is mapped to.
