None of the domains have Cloudflare nameservers set at the registrar. Log in to your registrar, or contact them, to replace the nameservers currently in use with the 2 Cloudflare nameservers allocated for each domain…

Make sure you are updating the authoratitive nameservers and not adding NS records to your DNS.

I know, I moved them back right away. But now I cant work on them.

This happened when I moved them here yesterday.

I still need help on fixing this.

Make sure your DNS records are set correctly set up in your Cloudflare dashboard…
https://dash.cloudflare.com/?to=/:account/:zone/dns/records

Make sure your origin has a valid SSL certificate and that Cloudflare SSL/TLS is set to “Full (strict)”…
https://dash.cloudflare.com/?to=/:account/:zone/ssl-tls

If you have problems once setting the nameservers back to Cloudflare, set the DNS records to “DNS only” or pause Cloudflare which will mean Cloudflare is providing DNS only and post back. This saves keep changing the nameservers and any issues with the time that takes.
