DNS not being seen by PayPal via Talos. IP Address not found

PayPal cannot get name resolution through their DNS provider which is Talon running Cisco servers or something related to it. The check is https://talosintelligence.com/reputation_center/ for SovariaEstates.world which does not find any IP address. How is it possible that they cannot resolve the Domain name? There was no problem prior to relocating the domain to Cloudflare.
