c# application do not send requests without fiddler

Question

I have this application coded in c#. The application uses httpclient and webrequests methods.

The problem I am facing is when I run the application it do not actually send requests. But, when I run the fiddler then run the application it sends requests and works flawlessly. What could be the reason?

This sends request.

public void Login()
        {

            Loginfirst();

            //Create cookies

            // create request
            HttpWebRequest request = (HttpWebRequest)WebRequest.Create("http://www." + server_site + ".com/login");
            //request.CookieContainer = cookieJar;

            request.Method = "POST";
            string postData = "email=" + Username + "&password=" + Password + "&remember=false&request_type=ajax";
            byte[] byteArray = Encoding.UTF8.GetBytes(postData);


            //set the contenttype property
            request.ContentType = "application/x-www-form-urlencoded";
            request.ServicePoint.Expect100Continue = true;
            //request.AllowAutoRedirect = true;
            //set header
            request.UserAgent = User_Agent;
            request.Accept = "application/json";
            request.Headers.Add("X-Requested-with", "XMLHttpRequest");


            request.Headers.Add("Cookie", m_cookies);

            log_file("line 975" + m_cookies);


            //request.Headers["Cookie"] = "rlogin=" + Username + "";
            request.KeepAlive = false;
            //set the contentlength property of the WebRequest
            request.ContentLength = byteArray.Length;

            // get the stream containing returned by the server.
            Stream dataStream = request.GetRequestStream();
            // Write the data to the request stream
            dataStream.Write(byteArray, 0, byteArray.Length);
            //close the Stream object
            dataStream.Close();
            // get the response


            try

                HttpWebResponse response = (HttpWebResponse)request.GetResponse();

                cookieCount = cookieJar.Count;
                String setcookieheader = response.Headers[HttpResponseHeader.SetCookie];

                Console.WriteLine(setcookieheader);

                //display statuts
                //Console.WriteLine(((HttpWebResponse)response).StatusDescription);



                if (response.StatusCode == HttpStatusCode.OK)

                }
                else
                {
                    Login();

                }

                dataStream = response.GetResponseStream();
                //open the stream using a streamreader for easy access.
                StreamReader reader = new StreamReader(dataStream);
                //read the content

                response.Close();


            }
            catch (WebException e)
            {

                log_file("Line 1055" + e.Message);

                if (e.Status == WebExceptionStatus.Timeout)
                {
                    Login();
                    return;
                }
            }


            //dynamic result = JsonConvert.DeserializeObject(response_object);

t0 = new Task(bb0.Login);
                t0.Start();

    t1 = new Task(bb1.Login);
                t1.Start();
    t2 = new Task(bb2.Login);
                t2.Start();

Task t0 works without fiddler. Task t1 wont work without fiddler. Task t2 wont work without fiddler.

You can only successfully one task at a time. Like if you run t2 then cant work with t1, t2 vice verse.

This only creates the request object. You have to call GetResponse() or BeginGetResponse() to actually send the request to the server.

WebResponse reponse = request.GetResponse();
