Are you sure your analysis is correct? The SSL_get_cipher() call will return
NONE if the TLS handshake failed, so you may only see the symptom, not
the reason of your problem.
Please check the return values of your SSL_connect()/accept() calls
and check the error stack for error messages.
The OpenSSL library routines will always log an error message when something
is going wrong.
