Explore Creators on Ghost - ghost site not recognized as ghost

I’m trying to submit site:

to:

but there is message:

That ain’t gonna fly.
You’ll need to submit a site running on Ghost.

If I try another site: https://dataplotplus.com/ (which is with the same installation) I got success

  • Version: 5.19.1
  • browser Firefox

I don’t see errors in the logs.

If I try to submit the site from ghost admin I get message:

Something went wrong. Please try again or contact support@ghost.org

It looks like https://datascientyst.com/ghost/ has access control which prevents Ghost Explore from communicating with your site.

Thank you Vikas.

Both are behind CF with the same settings.
There is one more site in similar situation which is blocked too.

In the browser there is error:

POSThttps://ghost.org/explore/api/fetch-site/
[HTTP/2 500 Internal Server Error 306ms]

I think that WAF the firewall in CF might be the reason.
I was comparing only the page rules.

Thank you.
