nice, if it's stayed active for 22 minutes the start command is fixed.
to see it in a browser you need to give the service a public domain, it doesn't get one automatically:
- click your service
- go to Settings
- scroll to Networking → Public Networking
- click Generate Domain
- if it asks which port, put 8080 (or whatever $PORT is set to)
it'll give you a link ending in .up.railway.app, that's your site.
one thing to watch: if the page loads but says application failed to respond, that usually means gunicorn is bound to the wrong port, so double check your start command still has --bind 0.0.0.0:$PORT.

two separate things going on here.
the redeploy problem isn't you. there's an active incident right now, deployments stuck in a queued state across all regions, opened 19:50 UTC: https://status.railway.com/ — so give it time rather than retrying, your deploy is probably just sitting in the queue.
the crash is your start command. ModuleNotFoundError: No module named 'main' means gunicorn was told to load a file called main.py that doesn't exist. the part before the colon is the filename without .py, the part after is the Flask/FastAPI variable inside it.
so gunicorn app:app only works if your file is literally app.py and the app object inside it is called app. check your repo:
file is app.py, object is app → gunicorn app:app
file is main.py, object is app → gunicorn main:app
file is server.py, object is application → gunicorn server:application
if it's inside a folder, use dots, e.g. gunicorn src.app:app.
your bind looks right, keep --bind 0.0.0.0:$PORT.

Thank you for your response! I’ll check. I switched to my mobile device and it shows the deployment as active and it’s been active for over 22 minutes. My question now is this, how do I view my project in a web browser? Can’t seem to figure that out. I appreciate your expertise!
