I am trying to add SSL certificate for my NS gg.cloudns.be

$ host -t NS gg.cloudns.be
gg.cloudns.be name server dane.ns.cloudflare.com.
gg.cloudns.be name server meadow.ns.cloudflare.com.

when try to add certificate, it shows an error banner in the DevilWeb UI.

You are showing us that you set NS records pointing to Cloudflare. I don't quite understand what you mean by attempting to generate Let's Encrypt certificates for NS records.
