I verified that the health ping runs on docker desktop, and not seemingly able to do this here. Not sure what settings this requires, likely need feedback directly from Railway.

The health check Railway runs upon starting your app is not a ping, it is a GET request.

Yes, pardon the phrasing that was meant more as shorthand rather than saying "The get request happening on my app is failing." But according to the logs per the last deployment:

1/1 replicas never became healthy!

Healthcheck failed!

However in the asp.net program.cs both are setup, and the GET request, as I said this runs when I use it on docker desktop. When the request runs locally on railway it fails.builder.Services.AddHealthChecks();app.UseHealthChecks("/health");

Is your app listening on the host 0.0.0.0 and the PORT environment variable?

The PORT variable is set to 5000, and inside the appsettings is this: "Kestrel": {

"Endpoints": {

"Http": {

"Url": "http://0.0.0.0:5000"

},

"Https": {

"Url": "https://0.0.0.0:5001"

}

}

},

"AllowedHosts": "*"

As mentioned, your app needs to listen on the PORT environment variable.

The app is currently hardcoded to do this for testing on railway:app.Run("http://0.0.0.0:5000;https://0.0.0.0:5001");

Your app needs to listen on the PORT environment variable.

The port environment variable is currently set in both the config, and on railway, as 5000.

I suppose since I've never used railway before, and all the other services I use seem to work; it would be beneficial for me if, I was told what configuration options need to be setup on the app and/or inside railway rather than just telling me the app needs to be listening to a PORT env var, when it already is.
