Nancy Self Hosting - Service Unavailable - Win7

Question

I've scrapped what I was working with and went to the simplest of code:

class Program
{
    static void Main(string[] args)
    {
        var nancyHost = new Nancy.Hosting.Self.NancyHost(new   Uri("http://localhost:8080"));
        nancyHost.Start();

        Console.ReadLine();
        nancyHost.Stop();
    }
}
public class MainModule : Nancy.NancyModule
{
    public MainModule()
    {
        Get["/"] = x =>
        {
            return "Hello world!";
        };
    }
}

When I browse to

   http://localhost:8080

I get:

---

Service Unavailable

HTTP Error 503. The service is unavailable.

---

I've tried several solutions. Including several variations on: Remote access to a Nancy Self Host

Any ideas?

Answer 1

Make sure you are running Visual Studio as Administrator and that 8080 is not used by something else at the same time. Have a look at the self-hosting demo which sets up a couple of different URIs for a self-hosted application https://github.com/NancyFx/Nancy/blob/master/src/Nancy.Demo.Hosting.Self/Program.cs#L12

Answer 2

I don't how much value this answer will have, but I did encounter this same 503 error when I started Nancy with this combination of settings:

_nancyHost = new NancyHost(new HostConfiguration { 
        RewriteLocalhost = false
    }, 
    new Uri(string.Format("http://localhost:{0}", port)));

The error was encountered when using a local browser accessing http://localhost:3684/ to Nancy running in a Windows Service as Local System

The prior revision with RewriteLocalHost on default setting of true had been working. This was one of the things I was trying while attempting to diagnose my question here: How do I remotely access self-hosted Nancy service?
