If certificate check fails, SSL_Connect will fail, thus the removed code will not run. It would only runs when successful. That function is meant to check the error code when there is a certificate validation issue. SSL_get_verify_result is being used incorrectly here; it is intended to get the validation error reason when SSL_Connect fails, and that failure is due to an invalid certificate.

I would prefer that we add a separate connect() function which takes a sockaddr_in rather than a hostname.
This would encourage the use of SNI whenever possible.

But I think just checking for pOpensslCredentials->sniHostName != NULL should be sufficient here.

sniHostName == NULL should result in SNI being disabled rather than an explicit disableHostnameCheck.

This will allow demos to disable hostname checking, allowing them to be used with Greengrass or other endpoints that do not have the hostname in their certificate subject.
