The issue I am facing:
Getting the error:
;; communications error to 127.0.0.1#5335: timed out
;; communications error to 127.0.0.1#5335: timed out
;; communications error to 127.0.0.1#5335: timed out
when querying certain domains.
Details about my system:
RP5, with latest PiHole version running unbound.
What I have changed since installing Pi-hole:
Configured PiHole to use UnBound.
What's odd, is this works:

BUT, this fails:

However, if I force using 1.1.1.1 as the DNS resolver:

No errors seem to show up in my UnBound log.
