PiHole suddenly stopped forwarding DNS resolutions? No internet

That is the public IPv6 address of your router.

Your router is advertising its own IPv6 address as DNS server, allowing your clients to by-pass Pi-hole.

You'd have to find a way to configure your router to advertise your Pi-hole host machine's IPv6 as DNS server or to stop advertising its own.

You'd have to consult your router's documentation sources on further details for its IPv6 configuration options.

If your router doesn't support configuring IPv6 DNS, you could consider disabling IPv6 altogether.

If your router doesn't support that either, your clients will always be able to bypass Pi-hole via IPv6.

Ah ok, that's probably it then - my router does not support disabling IPv6 nor changing IPv6 DNS.

But how come that I can't connect to the internet when I have PiHole running? If it bypasses it, surely I should be able to still connect even with PiHole plugged into the network?
