The answer was linked above. You need something like this.

@riking

and editing the server_name and location stanza like this:

    server_name discourse.example.com;  # <-- change this

location / {
                proxy_pass http://unix:/var/discourse/shared/standalone/nginx.http.sock:;
                proxy_set_header Host $http_host;
                proxy_http_version 1.1;
                proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
                proxy_set_header X-Forwarded-Proto $scheme;
                proxy_set_header X-Real-IP $remote_addr;

}
