Block YouTube

If you don't see the YouTube accesses in the Web Filtering log file, then the traffic is going via UDP 443.  I believe you need only block that traffic outbound with a Firewall rule.  That will, as Sachin said, force the Google servers to communicate with TCP 443.  Please tell us if you also had to select 'Decrypt & scan' to make your block work.

Something like this?

I created a service for UDP over 443

Then I created a a firewall rule at the top.  I selected all my Internal Networks as sources and the Destination is Internat IPv4/IPv6. The Action is Drop.

I have not yet enabled it.  Wanted to bounce this off you 1st.

Looks good, Chris!

I just ran a test on my sons tablet.

It seems to work.  You tube itself loads... but videos do not play.

The docs I've seen also mention that Google uses UDP over port 80. I'm considering adding that to the rule as well.
