Possibly related to #4290, however in my case no IPv6 is involved.
tcpdump seems to confirm that AGH is not querying the configured upstream servers.
Here is a tcpdump of me doing nslookup 192.168.3.6 127.0.0.1:5353
22:10:38.659540 IP localhost.34339 > localhost.5353: 39891+ PTR (QM)? 6.3.168.192.in-addr.arpa. (42)
22:10:38.659681 IP localhost.5353 > localhost.34339: 39891* 1/0/0 PTR SEPxxxxxxxxxxxx.voice.gofferje.net. (90)
And here a tcpdump of me querying AGH with nslookup 192.168.3.6 127.0.0.1:53
:
22:13:39.683965 IP localhost.39241 > localhost.53: 13139+ PTR? 6.3.168.192.in-addr.arpa. (42)
22:13:39.685186 IP localhost.53 > localhost.39241: 13139 NXDomain* 0/1/0 (97)
AGH does not seem to query the upstream server 127.0.0.1:5353.

Installation
Custom package (OpenWrt, HomeAssistant, etc; please mention in the description)
Setup
On one machine
AdGuard Home version
v0.107.53
Action
I have AGH set up on OpenWRT. Because I have different subnets with different domain names, I have multiple instances of dnsmasq running: Port 5352 for 192.168.2.0/24 Port 5353 for 192.168.3.0/24
I can successfully resolve IP via those instances e.g. with
nslookup 192.168.3.6 127.0.0.1:5353
In AGH I have the following entries in my upstream servers list:
Additionally, I have the following configuration in the private reverse DNS servers list:
"Use private reverse DNS servers" is checked.
I can successfully resolve .iot.gofferje.net and .voice.gofferje.net via AGH but the reverse lookups fail with NXDOMAIN. As mentioned above, I can do the reverse lookup successfully when telling nslookup to contact the respective dnsmasq instance directly, so it appears to be a problem with AGH.
Expected result
Reverse lookup
Actual result
NXDOMAIN
