Feedback:

I have been struggling with Host Overrides not appearing to work for quite a while now. Finally got it resolved. For details, see https://forum.netgate.com/topic/170227/host-overrides-are-not-resolving-used-to

A single footnote could have saved a few years of frustration and a few days of diagnostics.

What I'd love to see is a troubleshooting footnote on this page that says if DNS appears to be working, but Host Overrides are not, then it's likely a browser or some intermediate networking device has DNS Over HTTPS turned on. (Thus, the DNS isn't being resolved by pfSense.)

( The solution is to turn it off. Or, get pfSense to do the DNS encryption, not a upstream device. An example of how to do that resides at https://www.netgate.com/blog/dns-over-tls-with-pfsense )
