Same goes to google,play store and other online apps. I tried to:-
1.Taking out the battery and putting it back on (doesn't work)
2.Turning off the phone and the turn it back on (doesn't work)
3.Turned of the wifi for several hrs and on it back (doesn't work)

It kind of sounds like you are locked to only connect to HTTP (port 80) and DNS (port 53) or there somehting else that restricts connection, check your router configuration
