DNS over HTTPS (DoH) is a new protocol that encrypts domain name system traffic bypassing DNS queries. The primary function is that the communication is encrypted helps to hide one’s online activities.

In the SCR 50AXE/USG LITE 60AX , there isn't an option to directly block DoH/DoT. However, you can ensure that wireless or wired clients point to the DNS server configured on the SCR 50AXE/USG LITE 60AX. This prevents them from using external DoH servers on Windows OS.

To do this, navigate to the Nebula Control Center and edit the LAN interface settings of the Security Router. Set the DNS server configuration to 'This Router'.
