Can't open non HTTPS websites on mobile network. (Android Lollipop on Nexus 5)

I recently updated my Nexus 5 to Lollipop. The problem is that when I am on a mobile network, I can ONLY open HTTPS websites. All the HTTP websites appear as a blank white page. When I am on WiFi, everything is fine. I am located in India, if that matters.

Any ideas why this might be happening?
