My internet connection is working properly. What is the reason for this issue?

Answer 1

This is due to the ubuntu version that I used, which is older version of ubuntu 12.04. I ran the same code in ubuntu later version it worked successfully. Since Im using npm i have no other choice than upgrading the ubuntu version. Hope npm will fix this backward capability issue in there future releases.
