All flows gone after fresh install

most of you had not read that the setting up has been a struggle for me and going down that rabbit hole of ideas causes more problems.

with that said

  1. i do not want to use docker.
  2. i want to use a raspberry pi and have nginx server and gui loaded on it and then use cloudflare .

my issue is only finding the tutorials that spends 85 percent explaining the process of reverse proxy and not enough detail on installing causing me problems.

as of now i have nginx , and nodejs , and nginx gui installed on the standalone pi. but i cant access the gui for the next step.

I honestly do appreciate the multiple incites , however if I keep bouncing between different software is going to be causing more issues.

so if someone has a good link that explains in detail how to install nginx,nodejs, and nginx Gui in detail only using a standard pi that is headless with no docker, container, ....
please point me in the correct direction.
cheers.
