Nut upsuser - Dec 2016 - Problem installing NUT on 16.04

I rebooted machine and nut cannot connect to the UPS.

Any messages from the kernel regarding USB HID drivers? (Check dmesg and/or
journalctl.)

journalctl:

Dec 09 21:28:49 amethi upsmon[2359]: UPS [CyberUPS1 at localhost]: connect 
failed: Connection failure: Connection refused


Now, I found out that if I do

service nut-server stop

service nut-server start

It works.


But this is how it is before those commands:
