I followed everything in your guide except for the firewall part since I thought that was only for security and can be done later when stuff actually works, and because even in the replies there were a couple of issues with it.

I set up nginx correctly with atleast Discourse, but I still can’t acces discourse. Do I have to do anything on the DNS side to be able to connect to the Discourse subdomain?
