Nut plugin: nut_connect: upscli_connect (localhost, 3493) failed: Connection failure: Connection refused

I have a APC AP9630 network card on my UPS and have configured my TrueNAS-13.0-U6.2 using the following parameters:

After this configuration and issuing the command upsc smt750, I receive all the values back from the UPS verifying that the connection is successful. Unfortunately, there’s no verification that this connection is successful upon restarting the UPS service under TrueNAS. As a matter of fact, the only log messages I see are the following:

And for the ultimate test, I pull the power plug from the wall momentarily but nothing shows in the logs in TrueNAS telling me that the UPS is on battery. No email notifications either even though I receive all others. I have made sure of that.

I have spent countless hours on this and have yet to find a solution. I have read nearly every thread on the subjet as of late.

Any ideas why this is happening?

Anyone?

When I built my NAS, I used Spearfoot’s resource guide to setup my APC.

I don’t have a APC networks card. I just plugged it straight to the MB USB port.

I think it is still applicable to CORE.

Did you look at the many posts on the Forum Archive that can be found by searching on “AP9630”? From a quick scan of them there were claimed successes though some limitations were suggested.
