@coyote1abe said in DNS over TLS Not Working?:

could you please be a little more specific about the change you made to system

Somewhere in the past, he changed the IP settings of his device ( a Windows PC ) from the default DHCP settings to a static setting.

Like this :

which means this windows device doesn't use pfSense at all for DNS .... because he asked 1.2.3.4 to be used.

He has undone that, and now all is well.
