代码在win7下没有问题，在win10下怎么调试都是超时，下面是代码：



                HttpWebRequest myRequest = null;

                myRequest = (HttpWebRequest)WebRequest.Create(url.ToString());

                ServicePointManager.SecurityProtocol = SecurityProtocolType.Tls12;//微信采用的是TLS12

                if (url.StartsWith("https", StringComparison.OrdinalIgnoreCase))

                {

                    ServicePointManager.ServerCertificateValidationCallback =

                            new RemoteCertificateValidationCallback(CheckValidationResult);

                }

                //myRequest.ServicePoint.Expect100Continue = true;

                //myRequest.AllowAutoRedirect = false;

                myRequest.Method = method;

                myRequest.ProtocolVersion = HttpVersion.Version10;

                if(timeout)

                    myRequest.Timeout = 7000;

                myRequest.KeepAlive = true;

                myRequest.CookieContainer = backcookie;

                myRequest.Headers.Add("Cookie", cookiesstr);

                myRequest.UserAgent = "Mozilla/5.0 (Macintosh; Intel Mac OS X 10_11_6) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/54.0.2840.71 Safari/537.36";

                myRequest.ContentType = (method == "POST" ? "application/json;charset=UTF-8" : "application/x-www-form-urlencoded");

                if (method != "GET")

                {

                    byte[] data = Encoding.UTF8.GetBytes(paramPost);

                    myRequest.ContentLength = data.Length;

                    using (Stream dataStream = myRequest.GetRequestStream())

                    {

                        dataStream.Write(data, 0, data.Length);

                        dataStream.Close();

                    }

                }

                HttpWebResponse myResponse = (HttpWebResponse)myRequest.GetResponse();//卡在这里，报错超时

访问这个链接获取uuid没有问题：https://login.weixin.qq.com/jslogin?appid=wx782c26e4c19acffb&redirect_uri=https:%2F%2Fwx.qq.com%2Fcgi-bin%2Fmmwebwx-bin%2Fwebwxnewloginpage&fun=new&lang=en_US&_=1452859503801
但从访问https://login.weixin.qq.com/qrcode/ uuid 开始就超时
包括后面的判断是否扫码都超时，实在不知道是什么原因了，求帮忙T.T
