resolver: DNS format error from

[Alex]

Hi,
I have a bind-9.18.7 system on fedora37 and having some strange errors with
some queries.

$ host info.apr.gov.rs
Host info.apr.gov.rs not found: 2(SERVFAIL)

in my bind logs I have the following:
16-May-2023 10:37:49.800 resolver: DNS format error from 195.178.56.17#53
resolving ns1.apr.gov.rs/AAAA for <unknown>: server sent FORMERR
16-May-2023 10:37:49.800 lame-servers: received FORMERR resolving '
ns1.apr.gov.rs/AAAA/IN': 195.178.56.17#53
16-May-2023 10:37:49.800 lame-servers: timed out resolving '
info.apr.gov.rs/A/IN': 212.62.49.194#53
16-May-2023 10:37:49.800 query-errors: client @0x7f9d546d5168
127.0.0.1#59712 (info.apr.gov.rs): query failed (failure) for
info.apr.gov.rs/IN/A at ../../../lib/ns/query.c:7717

In the limited search results I've found for this, I believe it has
something to do with dnssec or EDNS, but I really don't know how to
troubleshoot this. Is this a known problem?

It also appears to be happening with even hosts like ticketmaster?
16-May-2023 10:21:09.348 lame-servers: FORMERR resolving '
engage.ticketmaster.com/NS/IN': 205.251.194.123#53

The host resolves fine on my bind-9.16.38 system using the exact same
configuration, as well as most or all public resolvers.
