Seeking help with Not finding devices

[genem2]

Hello all. I hope this is the right place for this, rather than creating an issue.

This tool was working great until it was accidentally removed a few weeks back, and now I'm pulling my hair out, trying to figure out why I can't get it rerunning.

I'm running unRAID 7.0.0 and the resulting container start command is:

docker run
  -d
  --name='hp_scan_to'
  --net='host'
  --pids-limit 2048
  -e TZ="America/Los_Angeles"
  -e HOST_OS="Unraid"
  -e HOST_HOSTNAME="ed800"
  -e HOST_CONTAINERNAME="hp_scan_to"
  -e 'IP'='192.168.0.45'
  -e 'RESOLUTION'='300'
  -e 'PATTERN'='yymmdd_hhMMss"-scan"'
  -e 'TZ'='America/Los_Angeles'
  -e 'PUID'='99'
  -e 'PGID'='100'
  -e 'LABEL'='Homeserver'
  -e 'NAME'='"HP ENVY 7640"'
  -e 'SUPPRESS_NO_CONFIG_WARNING'='false'
  -l net.unraid.docker.managed=dockerman
  -l net.unraid.docker.icon='https://homeassistant.genem.org/local/images/scanner.png'
  -v '/mnt/cache/HomeShare/':'/scan':'rw' 'docker.io/manuc66/node-hp-scan-to:master'

But this just terminates:

it runs, but isn't finding anything:

Searching device...

From the container. I can ping the printer at that IP address. A packet capture is not suggesting any firewall blockage. Not sure where to proceed...
