Add external subdomain

“Another site is already using this domain” error trying to set custom domain “” on site “lecardpainel”

Hi, @eliasportela, this custom domain ( is already configured on a different account. There is a limitation that a custom domain (including any subdomains) can only be used on single account.

Do you know who configured the site at Netlify? If so, the recommended solution would be to host the site above under their account/team. This would resolve the issue.

If there are other questions about this, please let us know.
