Hi @hengkiardo,

Your site is behind the CloudFlare CDN. The TLS-SNI-01 challenge method which is used by Certbot’s --apache or --nginx plugins does not work behind a CDN or reverse proxy, because it requires the incoming TLS session to be directly with your machine. You can instead use the HTTP-01 challenge method (used by Certbot’s --webroot plugin).

However, this should not usually result in the “handshake failure” error—are you sure that’s the exact error that you received?
