I think I missed this step after creating the CNAME it says "The record update takes some time to propagate depending on the time-to-live (TTL) values of the records. You can verify that the DNS records are working by visiting the domain name and confirming that the domain resolves to your IP address."
I assume I needed to wait for for the domain to resolve to the IP before doing the clean-up? Can anyone confirm? Thanks!
I'm still getting the same error. Can someone confirm whether or not following the clean up steps here https://cloud.google.com/dns/docs/quickstart#clean-up could be causing a problem? I didn't understand why you would setup an A and CNAME and then delete them and the zone? Thanks!
Thank you. It's failing for now, so I will give it more time. 
Trying to setup and test out Cloudron. I followed the instructions here https://cloud.google.com/dns/docs/quickstart to move my domain hosted on Google Domains to Google Cloud DNS. I created a service account key in JSON format and tried to upload and received queryNs ESERVFAIL. Any suggestions on what may have gone wrong? What I should check? I will also add that I performed the clean-up steps at the end of the instructions provided here https://cloud.google.com/dns/docs/quickstart#clean-up. Which had me deleting the A record and CNAME record and zone previously setup. I'm not a devops person, so I may have missed something obvious. Thanks for any help.
