Alexa can't discover the emulated hue and the devices

Hi everyone,

I am trying to get an Alexa integration via emulated_hue.

Version: Home Assistant Core (version | core-2021.12.8)
Hosting: Unraid - Docker
Network: Ubiquiti - with VLAN (but at the moment with open communication between all VLAN’s)

Hue Emulated Configuration:

host_ip: 192.168.X.X.  <-- my Home Assistant IP
listen_port: 80
expose_by_default: false
exposed_domains:
  - switch
entities:
  switch.on_off_plug_in_unit_3:
    name: Weihnachtsstern
    hidden: false

I can open the following URLs (Also over the same wireless network which Alexa (Echo) use) :
http://192.168.X.X/description.xml with the result:

<root xmlns="urn:schemas-upnp-org:device-1-0">

</device>
</root>

http://192.168.XX.XX/api/pi/lights with the result:

{"1": {"state": {"on": false, "reachable": true, "mode": "homeautomation"}, "name": "Weihnachtsstern", "uniqueid": "00:02:65:d0:aa:6a:XX:XX-XX", "manufacturername": "Home Assistant", "swversion": "123", "type": "On/Off light", "productname": "On/Off light", "modelid": "HASS321"}}

To me, it looks like emulated hue is configured correctly.
Unfortunately, when I search for a new Hue gateway or light via Alex, no device is found.

Of course, I used the search before but did not find a solution. Does anyone have an idea or a tip for me?

Cheers,
Danny

Hello and welcome to the forums!

But you are exposing a switch.
