@Jack69 -- We have this exact issue ...

The cable-modem could be blocking by IP-address, not by the FQDN (Fully Qualified Domain Name), namely www.youtube.com

$ nslookup www.youtube.com

Name:    youtube-ui.l.google.com
Addresses:  

          172.217.3.206
          172.217.14.206
          172.217.14.238
          216.58.217.46
Aliases:  www.youtube.com

So, are you blocking all of the above IP-addresses?

I sometimes change password of internet for short period of time and share only with my husband or restart modem and share password only with my husband. I put old password again when my son is out-of that zone of bad youtube
