No Internet Connection in TTY

Hello,

I installed leap 42.1 with X Window.

Trying to install Cinnamon desktop with zypper as described here: https://en.opensuse.org/Portal:Cinnamon

But getting an error of connection failed when I enter as root: zypper ar -r http://download.opensuse.org/repositories/X11:/Cinnamon:/Current/openSUSE_Leap_42.1/X11:Cinnamon:Current.repo

Using Ethernet connection.

Any help would be appreciated.
