The hostname does NOT match the Common Name in the certificate

Please help. I have an ssl certificate installed in one of my domains but it does not work. I get this message “the hostname (onakuviwa.co.za) does NOT match the Common Name in the certificate (server1.uungu.co.za). This certificate is currently invalid for this host.”

Have you tried installing a certificate that includes the correct hostname for that site? You currently have installed a certificate that doesn’t contain that particular hostname.

I have installed it using hestia server.
