tls_connection.erl appeared in R16B01. I'm not sure how you could have
got that error using R16B. If you are using a patched Erlang VM then
that might be part of the problem.

The "certificate unknown" error is very generic, according to the
OpenSSL documentation: "Some other (unspecified) issue arose in
processing the certificate, rendering it unacceptable."

I would suggest using the techniques described in
to acquire more diagnostic information.
Do you get the same error with a certificate that you generate yourself?
