The first thing that jumps out at me reading this over is that while you’ve defined an upstream server pointing to a socket file, the proxy pass is actually pointing to localhost port 8000. It should look like:
location / {
proxy_pass_header Server;
proxy_set_header Host $http_host;
proxy_redirect off;
proxy_set_header X-Real-IP $remote_addr;
proxy_set_header X-Scheme $scheme;
proxy_connect_timeout 10;
proxy_read_timeout 10;
proxy_pass http://helena_server;
}
Though, it seems that there must be something else going on here as normally I’d expect this configuration to display a 502 Bad Gateway error rather than the Nginx default page. Is it possible you have another Nginx configuration in /etc/nginx/sites-enabled/ that is taking precedence?
