I have an RPi running docker containers of NUT (upshift/nut-upsd:2.8.0) for each UPS I have in my UPS farm. Each UPS is exposed to an individual port for clients to hook on to and monitor - e.g. NAS, HA, etc. However, I just can't seem to connect my UnRAID NAS (7.1.4) with the 2025.09.07 plugin to any of the NUT instances. my other non UnRAID clients are working and can see battery charge, voltage, etc.. My NUT Settings ( I get an error when trying to create the NUT debug package :( ERROR: The NUT Debug Package Generation Script has failed - no response from the bash backend. ) Network UPS Tools Backend: nut-2.8.4-x86_64-1stable.ssl31

Oct 27 08:59:08 INX-NAS4 upsmon[1830989]: [D4:1830989] Beginning 5-sec delay between main loop cyclesi.e. it clearly sees on this UPS (an APC BGM2200B-GR) it's OL and DISCHARGing. But no update of any details anywhere on UnRAID I do see the upsnotify failure and also have that backend issue creating the debug package and wonder if it's some permission setting somewhere gone wrong. I have tried removing and reinstalling the plugin several times on 2 different UnRAID NASes with identical results and am not even sure where to look next. Any help on getting this working greatly appreciated.
