TLS v1.2 Handshake failure

Our Development Environment has been configured to use TLS 1.2 .  After the change we noticed that all SOAP Based Web Service requests fail with a handshake failure error. The REST Web Service Requests all work just fine. Is there a difference in the way OutSystems handles authentication handshakes for REST vs SOAP?

Our Environment is OutSystems


Sorry to "not add anything much relevant" here but I've had cases in the past in which a SOAP Webservice (with the same specification) would work really well in .NET but it didn't allowed me to publish on Java! So, I'll blame Java for this. :D
