Guys I have similar problem for three days and couldn't figure it out because I was using my university's internet, but at last I managed to solve that problem. the problem is your COMPANY INTERNET'S PROXY SERVER is blocking your communication, disconnect from YOUR COMPANY and use your own private data connection MODEM whenever you want to install themes, widgets, etc , problem solved. enjoy.
