Question

来自Google云消息传递服务器的响应“正常”，但响应正文显示“您已经从无法识别的IP地址浏览过。因此代理拒绝访问此网站或网页：”

    private static  string SendGCMNotification(string apiKey, string postData, string postDataContentType = "application/json")
    {
        ServicePointManager.ServerCertificateValidationCallback += new RemoteCertificateValidationCallback(ValidateServerCertificate);

        //
        //  MESSAGE CONTENT
        byte[] byteArray = Encoding.UTF8.GetBytes(postData);

        //
        //  CREATE REQUEST
        HttpWebRequest Request = (HttpWebRequest)WebRequest.Create("https://android.googleapis.com/gcm/send");
        Request.Method = "POST";
        Request.KeepAlive = false;
        Request.ContentType = postDataContentType;
        Request.Headers.Add(string.Format("Authorization: key={0}", apiKey));
        Request.ContentLength = byteArray.Length;
        Request.UserAgent = "Mozilla/5.0 (Windows NT 6.1; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/52.0.2743.116 Safari/537.36";
        Stream dataStream = Request.GetRequestStream();
        dataStream.Write(byteArray, 0, byteArray.Length);
        dataStream.Close();

        //
        //  SEND MESSAGE
        try
        {
            WebResponse Response = Request.GetResponse();
            HttpStatusCode ResponseCode = ((HttpWebResponse)Response).StatusCode;
            if (ResponseCode.Equals(HttpStatusCode.Unauthorized) || ResponseCode.Equals(HttpStatusCode.Forbidden))
            {
                var text = "Unauthorized - need new token";
            }
            else if (!ResponseCode.Equals(HttpStatusCode.OK))
            {
                var text = "Response from web service isn't OK";
            }

            StreamReader Reader = new StreamReader(Response.GetResponseStream());
            string responseLine = Reader.ReadToEnd();
            Reader.Close();

            return responseLine;
        }
        catch (Exception e)
        {
        }
        return "error";
    }

    public static bool ValidateServerCertificate(object sender, X509Certificate certificate, X509Chain chain, SslPolicyErrors sslPolicyErrors)
    {
        return true;
    }

非常感谢任何帮助。提前致谢

请注意来自Implementing an HTTP Connection Server的声明：

如果您的组织有防火墙限制流量或从Internet，您需要将其配置为允许连接 GCM，以便您的GCM客户端应用程序接收消息。港口打开的是：5228,5229和5230. GCM通常只使用5228，但是它有时使用5229和5230. GCM不提供特定的IP，所以您应该允许防火墙接受对所有人的传出连接 Google的ASN中列出的IP块中包含的IP地址 15169

来自Google Cloud Messaging Server的回复没问题，但Response Body说“无法识别的IP地址”
