        location / {
                proxy_set_header X-Real-IP $remote_addr;
                proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
                proxy_set_header Host $http_host;
                proxy_set_header X-NginX-Proxy true;
 
                # prevents 502 bad gateway error
                proxy_buffers 8 32k;
                proxy_buffer_size 64k;
 
                proxy_pass http://127.0.0.1:8080;
                proxy_redirect off;
 
                # enables WS support
                proxy_http_version 1.1;
                proxy_set_header Upgrade $http_upgrade;

        }
