CNAME cross-user banned when setting up a custom domain for a Page project

So I want to add a custom domain (A subdomian. The root domain has already been added to Cloudflare before) for a Pages project. After adding the custom domain, the Page project said my custom domain

Inactive (error)

Inactive (error)

. I then looked up the

Cloudflare Dashboard > My Domain > DNS

Cloudflare Dashboard > My Domain > DNS

, I noticed that the Cloudflare have correctly added a Orange-clouded CNAME (to

[project id].pages.dev

[project id].pages.dev

) record.

But when I visiting the custom domain I just added, an error pages rendered says

Error 1014 CNAME cross-user banned

Error 1014 CNAME cross-user banned

If the custom domain still says inactive (error) then I wouldn’t expect it to work - does it now say active?

No it hasn't. How long should I expect it to become

active

active

?

I've setup the root domain on Cloudflare (I am using other Cloudflare products), so I should not have worried about DNS propogation, SSL certificate (as I am using Universal SSL) or anything else.

Error usually means something went wrong rather than that it’ll fix itself - open devtools, find the network request that checks the custom domains status & see what the actual response is behind the error status

Ah I see. Let me check that.

The actual error message is

The domain is incorrectly configured

The domain is incorrectly configured

. The SSL CA is

lets_encrypt

lets_encrypt

and the verification status was

Well, what's the Custom Domain you're trying to add? Either it's not pointed at it, or something else like DNSSEC is broken with it

It is not likely. My domain is already added on Cloudflare. The domain's nameserver is also pointed at Cloudflare already. Cloudflare should have setup my DNS record automatically.

In fact I am able to see

Error 1014 CNAME cross-user banned

Error 1014 CNAME cross-user banned

, which means the Cloudflare has setup DNS correctly. But for some reason that custom domain is not active by Cloudflare Pages.

It's impossible for me to even begin to debug without knowing the domain, so can you share that either here or privately?
