「リモート側がトランスポートストリームを閉じたために認証に失敗しました。」 APIトラッキングを呼び出す際には、UPSトラッキングレストサービス

Question

私はasp.net mvc 5アプリケーションでUPSトラッキングAPIを実装しています。私は以下の方法で作成しました。

public virtual Core.UPSTrackingResponse.UPSTrackingResponse TrackUPS(string trackingNumber) 
{ 
    Core.UPSTrackingRequest.UPSTrackingRequest requestModal = new Core.UPSTrackingRequest.UPSTrackingRequest(); 
    requestModal.UPSSecurity.ServiceAccessToken.AccessLicenseNumber = UPSAccessKey; 
    requestModal.UPSSecurity.UsernameToken.Username = UPSUserId; 
    requestModal.UPSSecurity.UsernameToken.Password = UPSPassword; 
    requestModal.TrackRequest.InquiryNumber = trackingNumber; 
    requestModal.TrackRequest.Request.RequestOption = "1"; 
    requestModal.TrackRequest.Request.TransactionReference.CustomerContext = trackingNumber + " tracking context"; 

    string Data = new JavaScriptSerializer().Serialize(requestModal); 
    string response = ""; 
    System.Net.ServicePointManager.SecurityProtocol = SecurityProtocolType.Ssl3 | SecurityProtocolType.Tls12 | SecurityProtocolType.Tls11 | SecurityProtocolType.Tls; 
    HttpWebRequest request = (HttpWebRequest)WebRequest.Create(UPSTrackingURL); // https://wwwcie.ups.com/rest/Track 
    request.Method = "POST"; 
    request.KeepAlive = false; 
    request.ProtocolVersion = HttpVersion.Version10; 

    request.ContentType = @"application/json"; 
    request.ContentLength = Data.Length; 

    StreamWriter requestWriter = new StreamWriter(request.GetRequestStream(), System.Text.Encoding.ASCII); 
    requestWriter.Write(Data); 
    requestWriter.Close(); 

    try 
    { 
     WebResponse webResponse = request.GetResponse(); 
     Stream webStream = webResponse.GetResponseStream(); 
     StreamReader responseReader = new StreamReader(webStream); 
     response = responseReader.ReadToEnd(); 
     Console.Out.WriteLine(response); 
     responseReader.Close(); 
     Nop.Core.UPSTrackingResponse.UPSTrackingResponse ResponseModal = 
      new JavaScriptSerializer().Deserialize<Nop.Core.UPSTrackingResponse.UPSTrackingResponse>(response); 
     return ResponseModal; 
    } 
    catch (Exception ex) 
    { 
     return null; 
    } 
} 

これはローカルマシンから呼び出すときに問題なく動作します。 AWSサーバーにアプリケーションをデプロイしても、それは私にはあまり例外を与えません。理由は何か、私は今固執しています。

前にWebサービスへの呼び出しを行うには、コード内でこのどこかを追加してみてください：

    System.Net.ServicePointManager.SecurityProtocol = System.Net.SecurityProtocolType.Ssl3 
             | System.Net.SecurityProtocolType.Tls 
             | System.Net.SecurityProtocolType.Tls11 
             | System.Net.SecurityProtocolType.Tls12;
