[Nut-upsuser] unable to connect to APC UPS Connection Refused

As a wild guess, your `upsd.conf` tells it to listen on `127.0.0.1`
explicitly, which may be why it refuses to listen on wildcard `0.0.0.0`.
However the clients connect to `localhost`.
How is the system name resolution set up (check `/etc/hosts` as a starting
point) - can `localhost` there mean IPv6 `::1` as well (or even
exclusively)?
Good luck,
Jim
