I had a set Up with Node.js Application on Ubuntu 14.04 [reverse proxy]. Everything works fine..Hello world node application is running pretty well.. and am using pm2..

Now i have to run real world node application with serving index.html... i update the hello.js and upload it via SFTP and restart the nginx Ubuntu server. But its not working. Still it shows intial hello world application.

How do i proceed further. Thanks i advance
