I have a Windows .Netframework 4.5 app that I am trying to connect to a Python TLS server using a simple TlsClientSocket(). After successfully connecting, I call the socket.Negotiate() function and receive a TlsException with an ProtocolCode of 10 and a message of 'Unexpected Message'
What does this normally imply? I can successfully connect my python server to a python client and negotiate to TLS 1.3 but every time I try it using the Rebex libraries I can only get 1.2 or this error.
Any assistance would be greatly appreciated,
