However I can't get brotli to be accepted in /etc/nginx/nginx.conf (as specified in the guide) and nginx you say I have it looking at port 80, but (a) I don't [at least not by my direction] and the guide does not specify anything regarding that. Clearly the guide is wrong and I will have to find another way to approach this.

If 80 and 443 are in use, you typically move on to the next set of
well known ports, like 8080 and 8443. Or you can use random port
numbers. You can move Apache or Nginx.
