No NUT web interface when TCP port is exposed

[barrelful]

Problem/Motivation

I am configuring the addon with Network port 3493, causing the port to be forwarded.

When I try to access on the browser HAOS-IP:3493, I see:

ERR INVALID-ARGUMENT
ERR UNKNOWN-COMMAND
ERR UNKNOWN-COMMAND
ERR UNKNOWN-COMMAND
ERR UNKNOWN-COMMAND
ERR UNKNOWN-COMMAND

Expected behavior

See a website with UPS info.

Actual behavior

Errors from the description.

Steps to reproduce

1. I install the addon, configure a device with:

   devices:
    - name: "EatonEllipseECO"
      driver: usbhid-ups
      port: auto
      config:
        - vendorid = 0463
        - product = "Ellipse ECO"
        - productid = FFFF

2. Add user, password and network port.

3. Start the addon.

Proposed changes

Not sure what the problem is exactly. When I add the integration it seems to be getting some basic info (not sure how reliably it is working though).
