Your deployment completed without failures, but we found no runtime logs, which strongly indicates your application isn't binding to the correct port. Railway injects a PORT environment variable that your app must use - make sure your application listens on process.env.PORT (or the equivalent in your language) and binds to 0.0.0.0 rather than localhost or 127.0.0.1. For example, in Node/Express this would be app.listen(process.env.PORT, "0.0.0.0"), or for Python with Uvicorn: uvicorn main:app --host 0.0.0.0 --port $PORT. You can verify your configuration in your service settings and check that any custom target port in your domain settings matches what your app actually listens on. More details are in our networking guide.
