NGINX not pointing to localhost

I can access my server running in a Docker container w/ port 0.0.0.0:8080 and 0.0.0.0:5432 (for accessing remote Postgres server on ElephantSQL). I had this running @ one point behind an NGINX server in DigitalOcean but had to recreate my droplet and now I can’t get the config to work again … ugh!.

I CAN access my server via http://dropletIP:8080

When I run my server in a container on my MCB and I run the following NGINX server & configuration on my MCB in another container, I access my server with http://localhost:80.

But when I run the same configuration and servers in my droplet: http://dropletIP:8080 … my server is working but MyDomain.com … server does does not response.

Also… I have MyDomain pointing its A record to www.MyDomain.com and MyDomain.com

Here is my default (no extension) which I have located in \etc\nginx\sites-enabled. (Note: there are no config files in config.d and the default file in sites-available is a mirror of the default config file in sites-enabled.

server {
    listen  [::]:80;
    server_name MyDomain.com www.MyDomain.com;

    location / {
        proxy_pass http://localhost:8080;
#       proxy_set_header Connection "upgrade";
#        proxy_set_header Host $host;
 #       proxy_set_header X-Real-IP $remote_addr;
 #       proxy_cache_bypass $http_upgrade;
 #       proxy_set_header Upgrade $http_upgrade;
        proxy_connect_timeout 60s;
        proxy_send_timeout 60s;
        proxy_read_timeout 60s;
    }
}

my ufw status:
