Unable to add a custom domain for my site

PLEASE help us help you by writing a good post!
Netlify Site:

  • we need to know your netlify site name. Example: gifted-antelope-58b104.netlify.app
  • DNS issues? Tell us the custom domain, tell us the error message! We can’t help if we don’t know your domain.

Domain below:

It says another site is using this domain.
so how can I apply that domain to my Netlify site? My domain provider is godaddy.com

  • Build problems? Link or paste the FULL build log & build settings screenshot

The better the post - the faster the answer.

Hey there, this is happening because the custom domain you’re trying to use already exists on Netlify under a different account.

If you have some idea of who might be using the domain (maybe a previous collaborator or an agency you’ve worked with in the past?), the quickest way to get this resolved is for you to contact that person directly and ask them to remove the domain from their account here:

https://app.netlify.com/sites/SITE-NAME/settings/domain#custom-domains > “Options” dropdown > “Remove domain”

If you’re not sure, please verify domain ownership and let us know by responding here when that’s done. If the verification is successful we can remove the domain from the other account so you can use it on yours.
