UPS Self-Test only erroring for some (same model)

There are two UPS entries that give me this error (ERR ACCESS-DENIED) when I run a self-test:

Error running command test.battery.start.quick, Error running: INSTCMD basement-network-closet-3 test.battery.start.quick: ERR ACCESS-DENIED

SSH

One of them, the Raspberry PI has 3 UPSs attached, and only the 3rd one has issues. If I run the command over SSH, it does work:

pi@ups-basement-network-closet:~ $ upscmd -u upsmon -p REDACTED basement-network-closet-3 test.battery.start.quick
OK

Oddly, it didn’t work for all 3 when I used the interactive method:

pi@ups-basement-network-closet:~ $ upscmd basement-network-closet-3 test.battery.start.quick
Username (pi): upsmon
Password:
Unexpected response from upsd: ERR ACCESS-DENIED

pi@ups-basement-network-closet:~ $ upscmd basement-network-closet-3 test.battery.start.quick
Username (pi): upsmon
Password: # I put no password this time.
Unexpected response from upsd: ERR PASSWORD-REQUIRED

pi@ups-basement-network-closet:~ $ upscmd basement-network-closet-2 test.battery.start.quick
Username (pi): upsmon
Password:
Unexpected response from upsd: ERR ACCESS-DENIED

pi@ups-basement-network-closet:~ $ upscmd basement-network-closet-1 test.battery.start.quick
Username (pi): upsmon
Password:
Unexpected response from upsd: ERR ACCESS-DENIED

pi@ups-basement-network-closet:~ $ sudo upscmd basement-network-closet-1 test.battery.start.quick
Username (root): upsmon
Password:
Unexpected response from upsd: ERR ACCESS-DENIED

Strangely, it worked when I was admin the other day.

Home Assistant

Config for that device uses the same user:

The user has the capability of running a self-test on that UPS as well:

pi@ups-basement-network-closet:~ $ upscmd -l basement-network-closet-3

What’s going on here? Why just this one and one other UPS?
