    Still no solution for this issue? I'm having the same problem when trying to allow Viber using the application security profile.

    Well, I had the same problem too. But, you can solve it by adding SSL from Network.Services Category in Application Override, then allow it. The drawback is it when you allow it, VPNs will be able to use and bypass the restrictions. Hope, it's helpful.

    Most application control profiles will require SSL Deep Inspection to work properly. You can see for the details of Viber it uses some unencrypted protocols (HTTP) and some encrypted (SSL). Without SSL Deep Inspection, Application Control will only see the unencrypted protocols for Viber and everything else will just be seen as "SSL". This is why the other user made it work by setting application override for SSL. This is not what you want to do tho as it will introduce other issues becuase a lot of things use SSL.
