    you may need to run

    debug content-filter https-domain-filter cache flush

    you may need to block from LAN to WAN UDP port 443

    you could block by FQDN address *googlevideo.com in the firewall

    You need to block YouTube by app patrol, but usg flex 50w doesn't have this feature. https://community.zyxel.com/en/discussion/14682/how-to-block-youtube-access-by-schedule

    If your sure UDP port 443 is blocked add the following to the list content filter:

    www.googlevideo.com

    googlevideo.com

    www.youtube.com

    youtube.com

    *.googlevideo*.com

    Then you must run command because USG stores allowed sites before you added them to Forbidden

    debug content-filter https-domain-filter cache flush
