As the title says… The PiHole is setup on my router with a static IP and as the sole DNS Client. IPv6 is DISABLED on the router AND on my computer network interface. DHCP and DNS on my computer point to the router. The network wireless configuration is standard (nothing fancy). But in spite of this, Windows 11 (ANY browser, Chromium or non-Chromium based) refuses to use the PiHole and will allow all web connections, even websites specifically added to the blocklist. Secure HTTP is NOT enabled in the browser. A Windows 10 computer in the home with the same network settings recognizes the PiHole blocking and behaves as expected. An Android phone connected to the same network behaves as expected (PiHole blocking works). I do an ipconfig /all and verify the working machine (Windows 10) and non-working machine (Windows 11) both have the wireless network interface pointing to the router. ipconfig /release /renew /flushdns, etc. commands after changes have no effect. Flushing network table and restarting PiHole DNS resolver has no effect. I also tried changing my Windows 11 DNS to point directly to the PiHole instead of the router. No effect. I’m out of ideas. I saw one or two other people seemed to have this issue but it either spontaneously resolved or else no solution was found. My issue has been going on for some time. Ideas?
