Social previews not showing when sharing link to social media

Zero Trust Access

Social previews not showing when sharing link to social media. Hotlink is disabled. No firewall rules set. Preview works when Cloudflare is paused. OG meta tags are present.

I have allowed IP access rule for Facebook ASN. But still don’t see the preview.
Here is the URL

It’s not allowing me to add the link. Not sure why.
