Eaton IPM NUT configuration

[AmIDoingSomething]

Hello,
I am currently trying to configure the UPS service in TrueNAS. I have setup the Eaton IPM appliance but I cannot get TrueNAS to work with it. I couldn't really find documentation about it so I am just stumbling around.
My current configuration in TrueNAS is:

Code:

General Options
Identifier: ups
UPS mode: Slave
Remote Host: 192.168.69.42
Remote Port: 3493
Port or Hostname: auto


Monitor
Monitor User: truenas => created a user in Eaton IPM
Monitor Password: **********


Shutdown
Shutdown Mode: UPS reaches low battery
Shutdown Timer: 300

When I start the service, I receive an e-mail from TrueNAS: Communcation with UPS ups lost.
systemctl status nut-monitor
UPS [ups@192.168.69.42:3493]: connect failed: Connection failure: Connection refused

In the Eaton IPM gui under systems I have search settings. There NUT is enabled.
Let me know if you need more information.
