To let you know after some playing around there is an error in your installer that is not installing the correct cerbot package on a fresh minimal install of Centos 7.9.
It's failing to install the following package to complete the SSL requriements coded into AMP.
yum install python-certbot-nginx
Once the package is installed the installer completes without errors.
