Can't Block Youtube on PAN 7.1.0

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

Re: Can't Block Youtube on PAN 7.1.0

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
