Pihole + Unbound cannot resolve specific domain

Suddenly I discover that some of my torrents went red with "hostname not found" and my desktop cannot resolve this specific domain:
https://rawkbawx.rocks/

Pihole query log says "OK (answered by localhost # 5335), SERVERFAIL)

Changed desktop dns to cloudflare and it works.

Then checked:

1st attempt:

dig rawkbawx.rocks @127.0.0.1 -p 5335

; <<>> DiG 9.16.42-Raspbian <<>> rawkbawx.rocks @127.0.0.1 -p 5335
;; global options: +cmd
;; connection timed out; no servers could be reached

2nd attempt:

dig rawkbawx.rocks @127.0.0.1 -p 5335

; <<>> DiG 9.16.42-Raspbian <<>> rawkbawx.rocks @127.0.0.1 -p 5335
;; global options: +cmd

I rebooted but nothing changed.
Any help?

It was working fine some hours ago.

Domain-specific failures are often related to maintenance work on the domain servers authoritative for that domain, or a switch of the domain's digital signatures (as used by DNSSEC validating resolvers like unbound), or sometimes misconfigurations.
Those kind of failures usually get sorted quickly by the domain's maintainers, i.e. they don't last for long.

Are you still observing that SERVFAIL?

No, I'm ok now. Actually, it was fine some hours after I made the post here.
Thank you!
