Problem with unbound and pi-hole
I followed the official guide for installing Unbound alongside Pi-hole for my network, see Setting up Pi-hole as a recursive DNS server solution
A week ago I first followed this guide with a fresh installed Raspbian (lite) and everything worked out of the box. But today I followed the guide again (with a fresh install also) for my Pi-Zero at home and I just can't get unbound to work...
dig pi-hole.net @127.0.0.1 -p 5353 I always get "SERVFAIL" and if I look at the unbound.service I either get:
unbound: [1187:0] info: failed to prime trust anchor -- could not fetch DNSKEY rrset . DNSKEY IN
or something along the line of
the anchor is NOT ok and could not be fixed
I have no idea why that keeps happening. I tried
sudo unbound-anchor -v -a /var/lib/unbound/root.key (and other possible remedies I found online - like uninstall / using unbound-user etc) to reset the root.key-file but the anchor still fails.
Any help would be appreciated!
