After fixing the errors yesterday I think all I have left to do is configure the NGINX reverse proxy.

Configure Reverse Proxy

Steps taken from domain registrar

• Add the A record: tandoor.domain.com > XXX.XXX.XXX.XXX

Steps performed on NGINX-01

• sudo nano /etc/nginx/sites-available/proxy.conf
• I add the following:

# Configuration for tandoor.domain.com
server {
    listen 443;
    server_name tandoor.domain.com;
    client_max_body_size 100M;
    location / {
        proxy_set_header Host $host;
        proxy_pass http://tandoor.domain.local:8017;
        proxy_redirect off;
        proxy_buffering off;
        proxy_http_version 1.1;
        proxy_set_header Upgrade $http_upgrade;
        proxy_set_header X-Real-IP $remote_addr;
        proxy_set_header X-Forwarded-Proto https;
        proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
        proxy_set_header Connection "upgrade";
    }
}

# Configuration for http on port 80 to redirect
    if ($host = tandoor.domain.com) {
        return 301 https://$host$request_uri;
    }

• I save the proxy.conf file
• sudo systemctl stop nginx
• sudo systemctl start nginx

Testing is successful once the DNS A record propagates. I only had a few minutes to put towards play today, so I'm glad I was able to get something accomplished.
