Specify TLS versions allowed for content requests from the CDN

The option specifies a list of allowed SSL/TLS protocol versions. The list cannot be empty. By default, the option is disabled, and all the protocol versions are allowed. Possible values (case sensitive):

SSLv3
TLSv1
TLSv1.1
TLSv1.2
TLSv1.3

To manage TLS versions option:

1. In the Gcore Customer Portal, navigate to CDN. You'll be directed to the CDN resources page.

2. Find the needed resource and click on its CNAME to open the settings.
