iOS 8 - Apps other than Safari won't accept Cyberoam certificate
I found this: Certificate error when using Chrome for iOS with company CA


  There is no way to add Certificate Authorities to Chrome.app on iOS.
  The only way to manage them is in Settings > General > Profiles.
  
  It seems like this is an issue with Chrome.app that's not resolved
  yet. See Chrome for iOS ignores trusted root CA certificate. You may
  get additional help by posting to the Google Chrome Forum (linked
  before).
