Getting Error 1014 CNAME Cross-User Banned despite only one account

I use CloudFlare for setting DNS of my domain athenaos.org. Currently I have 4 A records from @ to GitHub Pages IP address and a TXT for domain verification and MX for email domain. Now I'm trying to set a CNAME record for dev.athenaos.org that points to Notion website (athenaos.notion.site). I bought the domain by NameCheap and on it I didn't set any DNS record. Furthermore, I have only one CloudFlare account. Why am I getting this error?

notion.so also uses Cloudflare, so the cross-user ban is between your account and Notions Do they have an official custom domain feature you can use to verify the domain?

The fix for a 1014 is for the target zone (Notion in this case) to create a Custom Hostname on their end. Many services will abstract this to the user as a "custom domain" feature. I've not used Notion with a custom domain before so I don't know if that's something they offer You could also try unproxying the record pointing to Notion - does it work if you do that? I suspect it won't, but if it doesn't when unproxied that means it wouldn't have worked if you were not using Cloudflare either

The record in CF is already unproxed

Okay, then yeah This is a Notion issue Cloudflare on your zone is not doing anything special there, the error comes from their account

What should they do to solve?

They need to create a Custom Hostname for the domain If they support custom domains as a feature it might be in their UI somewhere, I'm not familiar with their product Otherwise, you will have to contact their support and ask them about it

Maybe if I use record A it could work (?) 😢
