I've been trying to create a zone file in Google Cloud but encountered the bellow error message.
The DNS name (or its child domains) may be reserved or registered already, prohibited by policy, or there may be no DNS name server shards remaining for the name. For more information see https://cloud.google.com/dns/quotas#nameserver_limits.
I used the domain before, but I shutdown the project.
Any solution please kindly help?
Yup. It appears that deleting projects does not remove the entry reservation.
Undelete the project(s), remove entries and then zone, re-delete project.
I am testing IaC so I probably have 30 deleted projects by now and have put together a script to do the above. I have not been able to find an existing one.
