How to resolve: "Please add a virtual host for port 80"

Hi;

Thanks, but I’m really not sure what you’re asking. All I am trying to
do is get a cert, and I get the error in the process. I use MAMP Pro for MacOS specifically because I don’t want to get into the minutiae of Apache configuration. That said, “wrapping the important directives around a …” doesn’t really give me any actionable information.

What, specifically can I edit, copy, delete, change <etc.> to fix the error that is generated by Certbot?

Thank you.
