In the My Zones section, you can see a list of your existing CDN zones. By using the Search Bar, you can easily locate a specific zone, and to manage it click on the cogwheel icon next to it.
You can enable, disable, or delete a CDN zone(s), as well as, to add Let’s Encrypt certificate (LE) for the additional domains (CNAME) added to your zone.
IMPORTANT! Please note that new certificates will be issued only for the additional domains (CNAMEs) for which LE or custom certificate is not installed at the moment of the request!
