Before assigning the IP address to a domain name, make sure that the domain is added to your CyberPanel.
As soon as the desired domain is added to the panel, in the Available functions section click on SSL and choose Hostname SSL:
Choose the domain name and click on Issue SSL:
That’s it! The hostname SSL is issued to the website and now you can access CyberPanel at https://domain.tld:8090, replacing domain.tld with your domain name.
