Local network addresses not resolved

[ktuulos]

My previous HA crashed and I had to re-install from 28-Feb-2023 version of haos_ova-9.5.vdi.zip.

My local network has plenty of dynamic IPs and they are handled well by router. For example, I am (and in previous HA installation I was) able to point to "shelly1-03.local", which resolves to this Shelly's IP address. Anyway, in this new HA installation, resolving of local addresses don't work any more.

I have tried to manually add my router's IP to DNS, but no help. Here are some experiments to show the situation.

[core-ssh ~]$ ping shelly1-03.local
ping: bad address 'shelly1-03.local'
[core-ssh ~]$ ping shelly1-03
ping: bad address 'shelly1-03'
[core-ssh ~]$ nslookup shelly1-03.local
Server:		127.0.0.11
Address:	127.0.0.11#53

*** Can't find shelly1-03.local: No answer

[core-ssh ~]$ nslookup shelly1-03.local 192.168.1.1

I have the same issue, but it was since upgrading HA OS to 10.0 (10.1 is also affected).

Local DNS resolution works fine for a number of hours, but then stops. I can conduct a successful local DNS lookup using nslookup if I specify an internal DNS server, but an nslookup without a server specified uses 127.0.0.11 and can resolve external addresses only.

My DNS options have always been set to use my internal DNS servers.

I've just performed a HA OS reboot and I can resolve local DNS addresses again. nslookup is still using 127.0.0.11 for its server, but it is working. I expect it will stop again in a few hours.
