Installed NodeBB can't access installation, Nginx setup & SSL
I created a new Ubuntu droplet with the Node.js one click install.
Followed this guide to have nodebb installed on the server https://nodebb.readthedocs.io/en/latest/installing/os/ubuntu.html
I created an A record to point the server to my subdomain community.intelisight.com and added same on cloudflare.
But when I try to access the installation (which was successful and the service shows as running) with this http://community.intelisight.com:4567 I get nothing.
When I say http://community.intelisight.com same thing, I’m simply unable to access the live site.
My questions are
a) What am I doing wrong? What do I need to do to see the nodebb installation?
b) Is there a guide showing how to use nginx as the proxy server so I don’t have to put in the port to access the website?
c) How can I setup a free Let’s Encrypt SSL on this installation?
