HAOS appending .local.hass.io to FQDNs intermittently, causing resolution errors #4434
Description
Describe the issue you are experiencing
Hi there, I have some REST sensors that work most of the time, but occasionally the call will fail, and the home assistant DNS logs show lines like this
[INFO] 172.30.32.1:40285 - 15142 "A IN proxmox.redacted.home.local.hass.io. udp 74 false 1232" NXDOMAIN qr,aa,rd 51 0.000113154s

This seems like a bug to me, but it's possible I have something misconfigured.
