Bumping this for a review

It’s not very clear that this is a TrueNAS issue from your post. What version of TrueNAS?

What model of APC Network UPS (is it using an add-in network card?)?

Can you start by posting a screenshot of the TrueNAS configuration page for the UPS service?

And you get that message on the console when you hit save on the service’s config screen?

Sure.

Version: Dragonfish-24.04.2.2

APC: SRT3000RMXLT with a AP9641 network card 3

This is a slave node, master is at 192.168.254.10 and another slave is at 192.168.254.18, both of these are unraid

Images below. It appears that by running the command manually I can establish a connection.

Thanks for the comprehensive response.
Regret that I’m a Core guy and cannot help on this Scale issue - hopefully someone with appropriate Scale knowledge will be able to chip in.
