CNAME Cross-User Banned
I’m trying to use the subdomain “status.skyfall.dev” to use it as a domain for a status page on my friend’s Uptime Kuma instance, which is behind Cloudflare. My domain is using Cloudflare for DNS too. However, I’m getting a “CNAME Cross-User Banned” error when visiting my site. How can I fix this?

Your friend needs to add your domain as a custom hostname to his account:

Cloudflare for SaaS · Cloudflare for Platforms docs
Cloudflare for SaaS allows you to extend the security and performance benefits of Cloudflare's network to your customers via their own custom or vanity domains.
Might be a silly question but would it work if his Uptime Kuma instance is on a subdomain too?
Shouldn't matter.
Got it, thanks!
