Install LE For Your CNAME

In the SSL section, the installed SSL/TLS certificates will be displayed.

Universal CDN supports automatic installation of LetsEncrypt (LE) certificates for all custom aliases (CNAME) added to the CDN zones.

To install the LetsEncrypt certificate for all CNAMEs for a CDN zone, follow the steps outlined below: 

1. Log in to the Universal CDN Control Panel at

2. Navigate to the My Zones tab located in the top left corner.

3. Click on the LE button next to the CDN zone.

The process of installation and activation of the certificate may take several minutes. The system will install the LE certificate(s) for all CNAME(s) added.  

The color of the LE button will be changed to blue once the LetsEncrypt certificate is installed.

Please be advised 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.

The installed LetsEncrypt certificates will be renewed automatically by the CDN system. No further actions are required from your side.
