Error Connecting to Docker hub

Question

I have created a docker hub account and trying to connect on it to push an image. I am getting the following error:

>>>docker login -u <username> -p <password>  Error response from daemon: Get https://registry-1.docker.io/v2/: net/http: request canceled while waiting for connection (Client.Timeout exceeded while awaiting headers) 

I run this and i got the following message:

>>>curl https://registry-1.docker.io/v2/ {"errors":[{"code":"UNAUTHORIZED","message":"authentication required","detail":null}]} 

Also:

>>> env | grep -i proxy 

gave no result(means that i dont have proxy settings??)

>>> docker version Client: Version:      1.12.3 API version:  1.24 Go version:   go1.6.3 Git commit:   6b644ec Built:        Wed Oct 26 22:01:48 2016 OS/Arch:      linux/amd64  Server: Version:      1.12.3 API version:  1.24 Go version:   go1.6.3 Git commit:   6b644ec Built:        Wed Oct 26 22:01:48 2016 OS/Arch:      linux/amd64 

Any idea how to overpass that?

Modified DNS server setting to 8.8.8.8 and it worked.
