No public URL generated for Next.js app despite successful deployment
Body:
Hello Railway team,
I successfully deployed a Next.js 15.2.8 application using a custom Dockerfile and the start command:
npm run build && npm run start -- -p 3000.
The deployment shows "Active" and "Deployment successful", but no public URL (e.g., *.up.railway.app) is displayed in the dashboard.
The app listens on port 3000, as required. Could you please help me understand why the public endpoint is not being generated?
Repository: https://github.com/aaripinsky/voronezh-lawyer-seo-ready
Service name: voronezh-lawyer-seo-ready
Thank you for your support!
Best regards,
A. Ripinsky

you gotta do it manually, go to your service settings → scroll to "networking" section → click "generate domain"
that'll give you the *.up.railway.app url. also make sure your app listens on process.env.PORT instead of hardcoded 3000 in your start command, since railway injects the PORT variable automatically
