Ubuntu 22.04 php8.1-fpm wifth Apache - 403 Forbidden You don't have permission to access this resource

I installed php8.1-fpm on Ubuntu 22.04. In principle, I set everything up, but still "403 Forbidden You do not have permission to access this resource "error message is displayed. The system is configured on an internal network with a self-signed certificate for development purposes.

I've done it with virtualmin so far, but now I want to get used to it ... I bought the configuration basics from there, but obviously something is still missing
