I am trying to add custom domain
vibhav.festnimbus.com to my netlify site
https://vibhav-nimbus.netlify.app but it is showing
custom_domain is owned by another account.
The custom domain is successfully configured with Cloudflare as when I visit
vibhav.festnimbus.com it shows
But I didn’t add this domain to any other site. How can I overcome this issue?
