Question :
Why is the Content Filter not working and unable to block certain websites?
Answer :
Because the website may rely on DNS over HTTPS/TLS packets, the user needs to select the "drop" action for the "Action When Detecting DNS over HTTPS/TLS Packets" option in the DNS Threat Filter function.
