Unfortunately that has not worked for me either, still getting the same
error (error:14094438:SSL routines:SSL3_READ_BYTES:tlsv1 alert internal
error) each time.

I've tried using PEM and PKCS12 versions of the certificate file using 3
variations of each (1=Client, 2=Client+CA, 3=Client+CA+Root)

I've tried disabling the verification of the server certificates
made any difference, no luck with that either. Think I'm running out of
SSL related options to try!

Starting to think that I'm just not going to get this working...
