Our coporate website
blockdox.com is hosted by Netlify and has it’s own account (team). There is an A record pointing to the IP address and a CNAME for www pointing to the Netlify default subdomain. This works well.
I have three apps under a different account (team) and which I want to host on subdomains under a single Apex domain:
app.blockdox.com which has been active for several years, from before we moved the Apex domain to be hosted by Netlify. There is a CNAME pointing to
app.blockdox.com is registered in Netlify Custom Domains as the Primary domain. This works well.
I want to use admin.blockdox.com as a custom domain for
blockdox-admin.netlify.app noting that this is under a different account to the one that hosts the Apex domain. I added a CNAME for
admin.blockdox.com pointing to
When I use the form to add a custom domain I get an error " blockdox.com is already registered. If you registered this domain name through a different registrar, select Add domain to begin delegating it to Netlify."
app.blockdox.com work ok but this new custom domain isn’t allowed?
