Hello,

I just updated OPNsense to 26.1.8_5 from 26.1.6 and noticed the dashboard widget for NUT shows a message "Nut is not returning a status".

I went to System -> Nut -> Diagnostic and noticed the UPS Status page is empty. I'm currently runing the os-nut plugin version 1.9_1.

Below are the general and backend logs. Any help would be much appreciated.

Thanks

pkg lock nut

I just got a UPS that has USB output and was setting it up and I have the same blank diagnostic screen and errors in the backend logs.

running the revert and lock didn't seem to fix the errors or cause the diagnostic screen to work.

Instead of a dozen reports for OPNsense I think one to NUT may make a lot more sense:

https://github.com/networkupstools/nut/issues

FreeBSD ports doesn't appear to have any reports or movement on that particular subject.

this fixed my issue as well. THANKS!!! Interesting when trying to figure out why my NUT status was no longer working, Claude informed me that a UI bug has been around since 2021. Not sure if that's related or what but thanks for this temp fix anyway.
