HTTP Request must use TLS Protocol version 1.2

Hi,

In an AX2009 installation I have a HTTP request, to validate addresses through a UPS web service. This web service no longer accept TLS protocol version 1.0.

httpRequest = System.Net.WebRequest::Create(parameters.URL);
httpRequest.set_Method(‘POST’);
httpRequest.set_ContentType(‘application/x-www-form-urlencoded’);
httpRequest.set_ContentLength(data.get_Length());

stream = httpRequest.GetRequestStream();

The httpRequest.GetRequestStream() fails with an ClrError: The underlying connection was closed: an unexpected error occured on a send. Authentication failed because the remote party has closed"

To my knowlege ASx2009 is using 3.5 .Net Framework and in my method I don’t have the enum for TLS1.2 available like:

System.Net.ServicePointManager::set_SecurityProtocol(System.Net.SecurityProtocolType::Tls12);

I found another AX2012 related article:

https://blogs.msdn.microsoft.com/axsupport/2017/05/09/troubleshooting-errors-when-submitting-reports-to-the-digipoort-service-for-dutch-companies/

I did set the Registry settings that force TLS 1.2 version to be used by the .NET Framework, but I still not get TLS 1.2 being used. Using Microsoft Message Analyser, I can see that I still use TLS 1.0 version when the Handshake is made.

Any sugestions - tips for getting this to work ?

AOS OS: Windows 2008 Server R2 SP1, .Net framework 4.7 installed.

Thanks

Hi Jesper, do you find the solution for that problem ? We have the same problem too with TLS 1.2 for Ogone Credit Card Payment

Calls are still being made in TLS 1.0 (seen in Wireshark).

Do you have installed the update for .NET framework?

If you can’t get it working in .NET 3.5, consider creating a separate .NET 4.5+ process (such as a windows service) handling the communication.
