Thanks @user3259967
This did the job.
I would like to add that if you are behind a proxy that needs to be authenticated, you can add the username/password to your .bowerrc file.
{
"directory": "library",
"registry": "http://bower.herokuapp.com",
"proxy":"http://<USERNAME>:<PASSWORD>@<PROXY_IP>:<PROXY_PORT>/",
"https-proxy":"http://<USERNAME>:<PASSWORD>@<PROXY_IP>:<PROXY_PORT>/"
}
NOTICE the use of http:// in https-proxy
