I am on Google Cloud Platform and using Google Domains with Google Mail. I enabled Google Cloud DNS API, set up Networking - Cloud DNS - Record Sets.
I assume both of the Domain Name Servers should be the same, but when I change the values either from the Google Cloud Platform side or Google Domains, an error occurs.
When I change the Google Domain DNS from ns-cloud-c1.googledomains.com to ns-cloud-d1.googledomains.com, I receive an error message that states the following: "It looks like you've changed your name servers. All the settings for your domain (including website, email, synthetic records and resource records) are currently disabled. To enable these settings, you will need to restore the Google Domain Servers."
Does the DNS on the Google Cloud Platform and Google Domain/Mail have to be the same? Which DNS should go where?
ns-cloud-c1.googledomains.com
OR
ns-cloud-d1.googledomains.com
Do I need to add any resource records to Google Domains?
Thank you
