Troubleshooting custom domain, unable to create custom domain

Hi Netlify Support,

We are trying to point our custom domain at our netlify web app : wisc.netlify.app
We have the CNAME setup on the DNS server (The custom domain name is wisc.utm.utoronto.ca)

But when visiting wisc.utm.utoronto.ca, we are getting
Not Found - Request ID: 01G40MENVYVZJXS4883XJZBQ7Y

I think we need to create a Custom Domain but that returns
custom_domain is owned by another account

Any help is greatly appreciated.

Thanks.

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:

Netlify App > “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.
