Does, or did, Squarespace host the domain?

I want to use a third-party domain
www.sekar.co.id

This domain is no longer connected to any squarespace, but the error still says it is still connected

You have to log on to the third party domain service and change the name servers to squarespace from there. You can't change the name servers on the squarespace domain config panel. You will need to manage thru Solindo domain hosting provider.  This guide should help you:
