Error Setting Custom Domain on Cloudflare Pages: Need Assistance with APEX Domain C

I’m trying to set up a custom domain on Cloudflare Pages, but I’m encountering the following error message when attempting to configure an APEX domain (root domain): ‘That domain is already associated with an existing project. Use a different domain or find the project already using this domain and remove it.’ DNS is managed by Cloudflare, with only records for DNSSEC registered. What steps should I take to resolve this issue? I would appreciate specific solutions or advice.

Hi there,

This means someone already selected that pages address. Since This has to be unique, you need to select another one.
Note that this pages subdomain does not have to be shared if you have another domain with Cloudflare. You simply need to add the pages project as a custom domain:

Take care.
