Do you know if your application is statically linked or dynamically

Ive attached the code in question if it helps
Looks like the original developer already tried to print the contents
of the OpenSSL error stack:
case SSL_ERROR_SSL:
LOG(LOG_ERR, "%s: Error SSL_ERROR_SSL - return code: %d.
%s\n", custom_prefix, ret_val, custom_msg);
break;
}
ERR_print_errors_fp(stderr);fflush(stderr);
The errors seem to be going to "stderr" rather than via your "LOG"
function. You don't show what "LOG" does but if it goes somewhere
other than stderr then the errors are going somewhere different to
your log file. Are you able to show us the stderr output from running
your application?
