Can't Block Youtube on PAN 7.1.0

[dat.tran]

Hi Team,

I user PAN OS 7.1.0 and now i CAN'T block youtube although i try using both application and url to block.

1, Block by Application

I created a rule to block YouTube-base

I still view video on youtube normal 

In log traffic, i see Palo Alto Blocked Youtube-base application

But i think, traffic from youtube go through SSL and googbase app

 2. I user URL Cateogory

I created a URL for Youtube

And after i apply a policy block youtube by using url, 

On firefox, youtube is blocked

But on Chrome, Youtube still running

check your traffic log if you're seeing "quic" application, this is a sort of ssl over udp protocol google has implemented in chrome that can bypass your regular policy. you may want to disable quic in your browsers or block it altogether on the firewall

Please check the above document  if you do not want to make a change on the firewall if it works you can deny the same on the firewall.

type the below string  on chrome

chrome://flags

ctrl+f  search for quic and disable it, test the changes and  let us know.

Thank you
