My college network is secured with Cyberoam network. And Cyberoam requires a certificate it provides to be installed to access SSL secured websites. However, even after installing the certificate only Safari seems to be using the certificate and can open secure websites like Facebook. However other apps like Chrome, Facebook and Messenger won't work. I wonder why Chrome says Invalid Certificate Authority (see the screenshot below). The same certificate works well in PC.
I'm on iOS 8.1.4.
