Query regarding SSL_ERROR_SSL during SSL handshake

[Mahendra SP <mahendra.sp@xxxxxxxxx>]

Hi All,

We are using Openssl version 1.0.2h. When we call SSL_do_handshake, sometimes we notice that handshake fails with error SSL_ERROR_SSL. 

As per the documentation for this error, it is non recoverable and fatal error.  Documentation also mentions to check the error queue for further details. Does it mean, calling SSL_get_error after SSL_ERROR_SSL will give exact reason for this failure? 

Could you please let me know ways to identify the cause of this error?

Thanks

Mahendra
