Going to my domain (new-world.online) brings up:

Unable to connect
Firefox can't establish a connection to the server at new-world.online.

Pinging it on CMD-Promt brings up:

On my GoDaddy domain the hostnames are set to:
ns1.digitalocean.com
ns2.digitalocean.com
ns3digitalocean.com
I've left them 48 hours GoDaddy has confirmed they've been updated.

I've set @ to go to my droplet IPv4. And my CName * to point to my domain (@)
All set.

Typing in the IP: 104.236.37.92
Works and takes you to my site using the reverse proxy.
The reverse proxy has the domain set as new-world.online and is listening on 80 and connecting to the node app on port 8080.

I know this works because 104.236.37.92 works and not only 104.236.37.92:8080 proving the proxy works and it's the domain:
