HTTPS scanning mobile devices

I am trying to enable HTTPS decyrption and scanning for mobile devices in my network. I not sure what i am doing wrong but when i enable HTTPS scanning in the firewall rule browser traffic works fine. Able to go to google and keywords/content filter works and blocks/warns as expected. However apps on the devices like google play store apple store and others stop functioning. 

I have a chromebook and a iphone in my test firewall rule and both of them are showing the same symptoms. I have added exceptions in the exeptions tab for play.google.com, youtube etc. however when https scanning is enabled in the rule these apps stop working, as soon as i untick the checkmark they start functioning again, but of course then the google searches for keywords or content filtering then stop working. 

Someone please point me in the right direction here to get this working correclty on mobile devices, Android, apple, chromebooks

  • Jim,

    did you import the CA used for decrypt and scan on your mobile?

  • Yes i have imported the Sophos_SSLCA as well as the Defult certificate from the Sophos to my mobile devices. 

    Like i said i am able to use the browser fine and it will go to https sites with no cert errors. It is just apps on the device that do not seem to work when https scanning is enabled. 

    I can use the browser on my chromebook and go to play.google.com and it works fine. But from the google play app it acts like there is no internet connection. 

    Same on my iphone with the apple store.
