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?

What does "ldd" show you for the application binary? i.e.

ldd name-of-you-binary-here
