Hello All,

I tried to invoking Dynamics Nav Rest/OData web service in Asp.net and it's working perfectly when I was running in my local application.

After I published to IIS Server it's not getting the result it's throwing error Internal Server Error.

What I have tried:

I tried below code

public string GetData()
        {

            NetworkCredential networkCredential = new NetworkCredential("bojjaiah.thoti", "pass@word1", "testserver");

            using (var client = new HttpClient(new HttpClientHandler() { UseDefaultCredentials = true, Credentials = networkCredential, PreAuthenticate = true }))
            {
                ServicePointManager.ServerCertificateValidationCallback = new RemoteCertificateValidationCallback(delegate { return true; });
                Uri uri = new Uri("http://10.10.10.52:7148/DynamicsNav1/OData/");
                client.BaseAddress = uri;
                client.DefaultRequestHeaders.Accept.Clear();
                client.DefaultRequestHeaders.Accept.Add(new MediaTypeWithQualityHeaderValue("application/json"));
                

                string clarity_URL = "http://10.10.10.52:7148/DynamicsNav1/OData/ShopFloorTaskList";
                var response = client.GetAsync(clarity_URL).Result;

                string responseString = response.Content.ReadAsStringAsync().Result;
                Response.Write(responseString);
                return responseString;
            }
        }

I don't know what is the difference between local application and Hosted Application.

Please suggest us to work on IIS server.
