Unable to use AWS Route53 CNAME custom domain

I have a CF pages project with a custom domain added i.e.

foo.example.com

foo.example.com

. The domain

example.com

example.com

is set up with AWS nameservers, and it is not possible (powers that be) to migrate to CF DNS. So I set up a CNAME for the

foo

foo

subdomain with the value of my pages project URL.

However, it never passes through the DNS initialisation on CF.
(Please note values have been obscured, if you require genuine values please ask and i will DM.)

I can dig it:

➜ dig foo.example.com +short

foo.pages.dev.
172.66.44.231
172.66.47.25

➜ dig foo.example.com +short

foo.pages.dev.
172.66.44.231
172.66.47.25

but if i curl it:

➜ curl -vs foo.example.com           
*   Trying 172.66.47.25:80...

I can see on the CF docs that this HTTP 409/ CF1001 is setup issues, but does not describe any steps to remediate.

I dont believe there's anything on the aws Route53 to block this from working, but i have also contacted the aws team for support.

Is there anything on cloudflare that needs doing to resolve?
