        location / {
                proxy_pass http://127.0.0.1:9090/;
                root   html;
                index  index.html index.htm;
        }

        #error_page  404              /404.html;

        # redirect server error pages to the static page /50x.html
        #
        error_page   500 502 503 504  /50x.html;
        location = /50x.html {
