Read api result in asp.net

I am using the below C#/ASP.net code to get the weather data from the api. The api link works if I copy/paste it on the browser, returns all the data I want . But in my C# code, I get error "{"Unable to connect to the remote server"}"

Anyone knows what is wrong?

using System;
using System.Collections.Generic;
using System.Linq;
using System.Net;
using System.Web;
using System.Web.UI;
using System.Web.UI.WebControls;
using System.Runtime.Serialization.Json;
using System.IO;
using System.Text;
using System.Runtime.Serialization;
using System.Net.Http;
using System.Net.Http.Headers;
using System.Xml;

namespace WebApplication2
{
    public partial class GetData : System.Web.UI.Page
    {
        protected void Page_Load(object sender, EventArgs e)
        {

        }
        [System.Web.Services.WebMethod]
        public static  void getData()
        {


            var url = "http://api.openweathermap.org/data/2.5/forecast/city?id=524901&APPID=e67fab67a2bc61c221e8a6165965c107";
            var client = new HttpClient();

            client.DefaultRequestHeaders.Accept.Add(
                new MediaTypeWithQualityHeaderValue("application/json"));

            var response = client.GetAsync(url).Result;

        }

        protected void Button1_Click(object sender, EventArgs e)
        {
            getData();
        }  
    }

I noticed the issue was that my internet connection was using an internal dns server which its setting does not allow such a calls due to security restrictions. Outside our office, the code works just fine.

I'm not sure why you getting unable to connect remote server may be turning off your firewall solve your problem. try below code. https://stackoverflow.com/a/16642279/2745294 https://stackoverflow.com/a/5566981/2745294

string urlAddress = "http://api.openweathermap.org/data/2.5/forecast/city?id=524901&APPID=e67fab67a2bc61c221e8a6165965c107";

HttpWebRequest request = (HttpWebRequest)WebRequest.Create(urlAddress);
HttpWebResponse response = (HttpWebResponse)request.GetResponse();

if (response.StatusCode == HttpStatusCode.OK)
{
  Stream receiveStream = response.GetResponseStream();
  StreamReader readStream = null;

  if (response.CharacterSet == null)
  {
     readStream = new StreamReader(receiveStream);
  }
  else
  {
     readStream = new StreamReader(receiveStream, Encoding.GetEncoding(response.CharacterSet));
  }

  string data = readStream.ReadToEnd();

  response.Close();
  readStream.Close();
}
