I get error 1016 from your site which most likely means that your DNS record is a CNAME and what it is pointing to does not resolve.
Can you show a screenshot of your DNS records page here…
https://dash.cloudflare.com/?to=/:account/:zone/dns/records
Include the 2 Cloudflare nameservers at the bottom of that page. Your domain is set to use nameservers kip and rosa but another pair are being reported by the registry and a further pair are likely the active ones.

You may be in the wrong account for your domain, or have deleted and re-added the domain several times which will change the nameservers.
(Getting mix of 521 and 1016 so something is messed up, you need to ensure the correct nameservers are set).
