Custom domain already has an owner. Is it you?

Hello! I’d appreciate your help here.
I’m trying to add a custom domain to my site and a year ago (I guess) I did the same with the same domain, hence the error, but if I recall correctly it was from my own account, it wasn’t a different one and right now I only have one site online within my account.
I’ve read that I have to edit the txt record on my domain management service (namecheap in this case) and I have 3 values that can be edited, Host, Value and TTL. I don’t know where to edit Name with “verified-for-netlify”.
My netlify site is: https://norbert.netlify.app
My custom domain is: norbertstange.dev
What should I do now?
Thanks so much for your time.

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.
