@Changes to SSL for free subdomains

Reminder: “www” Subdomains Are Not Covered

Due to the way wildcard SSL certificates work, subdomains like www.example.ct.ws are not covered by the system-wide SSL certificate. Only direct subdomains (e.g., example.ct.ws) are supported.

If your site uses a www. subdomain, we recommend switching to the non-www version to ensure your visitors stay protected with HTTPS.

Existing custom certificates for www subdomains will continue to work until they expire. After that, they cannot be renewed.
