This is because of the proxy settings.
I also had the same problem, under which I could not use any of the modules which were fetching data from the internet.
There are simple steps to follow:
1. open the control panel
2. open internet options
3. under connection tab open LAN settings
4. go to advance settings and unmark everything, delete every proxy in there. Or u can just unmark the checkbox in proxy server this will also do the same
5. save all the settings by clicking ok.
you are done.
try to run the programme again, it must work
it worked for me at least
