When application control is used, replacement messages for some specific websites are not received.
Go to developer options in google chrome using 'Shift+Ctrl+I' and check the TLS version of websites like 'Youtube' or 'Facebook'.
It is normally version 1.3 for Google Chrome and version 1.2 for Internet Explorer.
As TLSv1.3 is not supported for inspection completely in FortiOS v6.0 or below, any website using version 1.3 will not processed by the FortiOS v6.0 or below properly causing no replacement message for them.
