WHOIS says there no IP for this domain

Hi All, I have a similar issue as far as I can guess, but I also have various audit data from the whois (UK nominet in my case) intoDNS website, and a print screen of the error that is not an error message, just says oops and the way the domain is configured at host server end the DNS config at Cloudflare end;
I also carefully checked SSL origin config. I am the only user of the cloudflare account. It is a free account.
WHOIS says there no IP for this domain
However, the Cloudflare a domain for @, www, and blog points to the host server dedicated IP (for a group of about 20 domains). All of this tend to show that the error is at Cloudflare end.

All of this tend to show that the error is at Cloudflare end.

Any idea or help would be greatly appreciated
