The security warning is most likely caused by a mismatch between the FQDN in the HTTPS certificate and the Web server FQDN. This can happen if the certificate is issued for a different domain or if the server hostname has been changed. The other options are not likely to cause a security warning. The TCP port number needs to be set to 443 for SSL/TLS encryption, the HTTPS encryption certificate needs to be installed on the Web server, and it is possible for a website to respond to both HTTP and HTTPS requests without causing a security warning.
