[Nut-upsuser] Unable to use the TCP network interface

[tyler.montney at wast3dgeneration.com]

*	Rasbian Buster Lite: latest
*	NUT version: latest
*	NUT installed from package manager
*	CyberPower CP1000PFCLCD via USB

 

Followed this article:
https://loganmarchione.com/2017/02/raspberry-pi-ups-monitor-with-nginx-web-m
onitoring/ "upsc" command works and outputs UPS data correctly.

 

My question regards the TCP network interface:
https://networkupstools.org/docs/developer-guide.chunked/ar01s09.html I can
connect and via netstat see the TCP connection is established. After writing
a command to the stream, when I read it times out.
