Thanks Bill.
Wondering why this would fail. The external make credential API,  I have
taken from tss2 GitHub only why would secret fail? When I ran all of this
locally it worked, the moment I moved the make external credential to the
server Im hitting this?
Can it be because of OpenSSL 1.1.0 required in tss2 and 1.0.2 version
running on my server?
Thanks
Rahul
