WEB API 2 Self-hosted hostname issues - binding

Question

I'am trying to make a self-hosted web api service. I followed a tutorial and it works fine on my local computer.
localhost/api/values responds fine with the expected JSON.
Now, I have a server binded to the DNS "myserver.mycompany.com". When I start my WebApi 2 service on this server and try to call myserver.mycompany.com/api/values I have a 404 page not found error.
If I browse locally on this server and call the localhost/api/values url it works fine.
Here is the code of the Startup class :
using Owin;
using System.Web.Http;
namespace SelfHostedWebApi2
{
public class Startup
{
// This code configures Web API. The Startup class is specified as a type
// parameter in the WebApp.Start method.
public void Configuration(IAppBuilder appBuilder)
{
// Configure Web API for self-host.
HttpConfiguration config = new HttpConfiguration();
config.Routes.MapHttpRoute(
name: "DefaultApi",
routeTemplate: "api/{controller}/{id}",
defaults: new { id = RouteParameter.Optional }
);
appBuilder.UseWebApi(config);
}
}
}
And here is how I start the server :
using Microsoft.Owin.Hosting;
using System;
using System.Net.Http;
namespace SelfHostedWebApi2
{
public class Program
{
static void Main()
{
string baseAddress = "http://localhost:80/";
// Start OWIN host
try
{
WebApp.Start<Startup>(new StartOptions(url: baseAddress));
HttpClient client = new HttpClient();
var response = client.GetAsync(baseAddress + "api/values").Result;
Console.WriteLine(response);
Console.WriteLine(response.Content.ReadAsStringAsync().Result);
}
catch (Exception ee)
{
Console.WriteLine("Erreur : " + ee.ToString());
}
Console.ReadLine();
}
}
}
Thank you for your help

You should change your baseAddress so that its endpoint matches your hostname or you may use a WeakWildcard * to match all possible hostnames.
This one should work: string baseAddress = "http://*:80/";
