failing with HTTP/2 1016 (Cloudflare origin DNS error

I’m stuck finishing a custom auth domain setup with Supabase.

• auth.aslax.eu is a CNAME (DNS only) pointing to my xxxx.supabase.co project
• No A/AAAA records for that host
• dig auth.aslax.eu resolves correctly to Supabase edge IPs

But health checks keep failing with HTTP/2 1016 (Cloudflare origin DNS error, Ray IDs like < ray id >).

If I switch back to the default xxxx.supabase.co host, everything works, so it looks like the custom domain’s certificate/edge routing isn’t fully set up. ( used to )

Any idea what I’m missing, or can someone from the team re-provision the custom auth domain? Happy to share more Ray IDs or logs if needed.
