Are you behind a firewall? We have those problems in our company where the firewall is blocking the request to the docker hub.

Yes I am in corporate n/w but using predefined proxy to bypass these firewalls, but still getting this error!!

Did you already search the forum for it? E.g. Docker : Installing Docker behind a proxy on CentOS 7 : Error while pulling image?
