  • Question

  • I have an Mvc application which depends on a web API application, I hosted the two on a shared hosting environment. API on the subdomain and Mvc on the main domain the API is api.mydomain.com and the Mvc is mydomain.com, the API works fine anytime I try it on postman or browser but the Mvc can not connect to it with the following error.

    This is how I connect to the API from Global.asax.cs  

        public class MvcApplication : System.Web.HttpApplication    {        protected void Application_Start()        {            AreaRegistration.RegisterAllAreas();            FilterConfig.RegisterGlobalFilters(GlobalFilters.Filters);            RouteConfig.RegisterRoutes(RouteTable.Routes);            BundleConfig.RegisterBundles(BundleTable.Bundles);            Proc.Configure("https://api.mydomain.com/");        }    }


    This Is How I call a resource

       
    public static class Proc    {       private static HttpClient _client;       public static void Configure(string Baseurl)        {            _client = new HttpClient();            _client.BaseAddress = new Uri(Baseurl);            _client.DefaultRequestHeaders.Clear();            //Define request data format              _client.DefaultRequestHeaders.Accept.Add(new MediaTypeWithQualityHeaderValue("application/json"));        }        public static async Task<T> Settings<T>()        {            if (!string.IsNullOrWhiteSpace(Account.AccessToken))                _client.DefaultRequestHeaders.Authorization = new AuthenticationHeaderValue("Bearer", Account.AccessToken);            var resp = await _client.GetAsync($"api/superadmin/settings");						var txt = await resp.Content.ReadAsStringAsync();            return JsonConvert.DeserializeObject<T>(txt);        }	}

    I'm able to connect to the live API from my local MVC application but I can not connect to the API from live MVC application.I will be glad to get some help.

  • This exception message says you're trying to connect to the same host ( 127.0.0.1 ), while you're stating that your server is running on a different host. This 127.0.0.1 represents a 'loopback' . It allows the computer to communicate with itself via network protocol .

    Dns.GetHostEntry(IPAddress.Loopback).HostName returns the host name of your machine. When you pass a host name to TcpClient , it will resolve it to one or more IP addresses using Dns.GetHostAddresses(hostName) . This includes the public and local IP addresses of your machine (e.g. 192.168.12.10), but not 127.0.0.1 (loopback address). So your client is trying to connect to any of the non-loopback addresses of your machine, while your server is listening only on the loopback address . So, no connection can be established. The solution to this problem is that connect to the same end point your server is listening on.
