Replacement message on Application Control

Hello,

I don't have any replacement message when Application Control profile block me.

Error : Website unavailable on Chrome

I'm running on FortiOS v6.0.5 on FortiGate 201E.

The inspection mode are in proxy.

I'v seen some tips about Web Filter Profile in flow-based when Web Filter and App Control are enable on a same rule.

I'v tried to create an other rule with only certificate-inspection and App Control on it.

Same result.

If someone have an idea.

Thank's guys!
