Getting "Authentication failed because the remote party has closed the transport stream." while making API call to UPS tracking Rest service

Question

I am implementing UPS tracking API in my asp.net mvc 5 application. I created below method.

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;
    }
}

This is working fine when i call it from my local machine. but when i deployed my application on AWS server, it keeps giving me below exception. What could be the reason, I'm stuck now.

Answer 1

Try adding this somewhere in the code, prior to making the call to the webservice:

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

Answer 2

If you have .NET 4.0 or .NET 3.5 answer of Alex K will not help as is. Best way to solve it is upgrade .NET.

If you can't upgrade: For .Net 4.0 use following code:

ServicePointManager.SecurityProtocol = (SecurityProtocolType)3072;

There is also a registry hack which forces 4.5 to use TLS 1.2 by default without enforcing it programmatically.

For .NET 3.5:

There is a recent patch available for .NET 3.5 which is enabling TLS1.2 support.
