CNAME record not working for Salesforce validation

What is the name of the domain?

eljna.au

What is the issue you’re encountering

CNAME validation not working and cannot see CNAME value using public DNS lookup

What steps have you taken to resolve the issue?

Raise support case with Cloudflare

Also - a bit more context

The CNAME record is set to “DNS Only” not proxied.

There are no other DNS record values in the ZONE so no A record as there is currently no website or other services - would this have any impact?

What’s the full hostname of the CNAME record?

Is just
eljna.au and value is “tlb9wxjbdpv-1m44bfybkjssm11y.click-sap.sfmc-marketing.com

You cannot use a CNAME at the zone apex. While you can create such a record in the DNS app in your dashboard, it will be flattened. That means Cloudflare resolves the name and publishes the IPs as A and AAAA records and not the CNAME record that your SaaS provider is looking for to validate your domain.

I only see an SOA and NS records for your domain. No A or AAAA records are returned. Can you share a screenshot of your DNS app in your dashboard?

Currently the only record is a CNAME value - no other A MX TXT etc values as the client has only just registered domain

Can you share a screenshot of the DNS from you dashboard? We should see that CNAME flattened into A and AAAA records and we don’t.

While you will likely need to use a subdomain in order to activate, it would be nice to figure out why your DNS is not published before you set up a subdomain.

It looks like your canonical name, aka, the target, does not resolve. That’s going to require a new approach. I recommend verifying the proper procedure with the Salesforce documentation. Hopefully you will notice something different this time. If the docs are public, you can always share a link here and we’ll check them out.

Thank you Kind Sir / Sirs

Cloudflare support has indeed suggested that a subdomain needs to be created and addding the CNAME record there as “Flattening” can be disabled for subdomains apparently.
