hi there

Here is a few things totry

1. Check deploy logs — click "deploy logs" in Railway to see why your app is failing
2. Verify port binding — your app must listen on process.env.PORT, not a hardcoded port
3. Test the Railway URL directly

• If it fails too → app issue (check logs, env vars, port)

• If it works → DNS/proxy issue

1. Disable Cloudflare proxy (if using it) — set the subdomain to DNS-only (grey cloud)
2. Wait 5–30 min for DNS propagation if records are new or try to re add them on your provider side

Most likely cause: Your app isn't binding to process.env.PORT or is crashing on startup. Check the Railway network logs first.
