Hello,
I have recently realised that mDNS resolution is no longer working on my NAS. As a result, the scheduled print job I have set up to keep my printer from drying out can no longer find the printer. I am not sure if the error comes from debian, armbian or omv. In this time debian 12.8 update landed. `avahi-browse` finds the machines, but `ping` or `ssh` do not. I tried running `omv-firstaid`and reconfiguring the network but it did not help either. Here is the output of `resolvectl status`:
Code
$ resolvectl status

Allegedly libnss-mdsn and systemd-resolved can interact in mysterious ways but I am not sure where to look next. Any help is appreciated.
