I think there is a difference between “Google Domains” and “Google Cloud DNS”. These are different and independent services at Google, however you might be able to transfer your Google Domain to Google Cloud DNS.

Perhaps you have registered a domain with Google Domain, but the LetsEncrypt currently uses an API meant to be used with “Google Cloud DNS” service. So, the error message is saying “Hey, I can’t find a managed zone defined with Google Cloud DNS”.

FWIW, you may still be able to use LetsEncrypt add-on by using the http method.

I moved to google.domain to cloudflare, was cheaper anyway
