I am currently facing a issue with my website after removing VentryShield, a popular L7 DDos Protection provider that is layered with Cloudflare from my domain. I removed their Custom Hostname TXT, ACME Challenge, and CName. After this, no traffic will work from my website, not even Cloudflare despite the name servers being untouched. I am not sure why this is happening, and I have attempted to put a Cloudflare Pages instance on the domain to see if that’ll fix it.
I have removed myself off VentryShield servers which proves it is not their issue as well as backed up by them.
