You can generate yourself a public domain in your service settings

Ah thanks I found it, after redeploying I get this error when going to the domain:

Not Found

The requested URL was not found on the server. If you entered the URL manually please check your spelling and try again.

Is your app listening on the PORT environment variable, or is the port hardcoded? If it's not reading the PORT environment variable, it's possible that Railway is expecting your app to use a different port.

For context, their own application is returning 404 at the root, Railway is not returning 404.

Thanks for the context Brody
I'm going to go ahead and mark as solved since the 404 is application-level, the original question has been answered and the OP isn't responding anyway

OP, if you do come back to this thread, the 404 issue is essentially an issue with your application itself and not an issue with Railway directly. You just need to find out why your application is returning that 404, likely a misconfiguration within your app somewhere - if you need further help then you unmark this thread as solved or open up a new thread

Happy holidays!
