Guidance needed: Setting up Google Domain with Google Cloud DNS and Lets Encrypt wildcard... possible?

That's for certbot, you want the docs for acme.sh.

indeed, but that link you posted, there is no mentioning for that google.json file with tthe service account
but why do you want me to test on another system? that lets encrypt addon just woks fine ??

this is the one i'm using

I really need to get some sleep - sorry
Maybe someone else can pick up where we left off.

ok, np, thnx in advance
