I just tried adding custom domain to my site but the HTTPS section under ‘Domain management’ says:
DNS verification failed
rootkea.me doesn’t appear to be served by Netlify
But I have already added Netlify nameservers to my registrar 3 days ago. Is this because I had set up DNSSEC with Cloudflare? My registrar still has that entry and http://dnsviz.net/d/rootkea.me/dnssec/ shows multiple errors which make my doubt stronger.
