Alexa integration via Emulated Hue does expose entities

Configuration
1

Dear community,

I am currently struggling with the Alexa integration via Emulated Hue.
Home Assistant is running in a docker container.
Here is my configuration.yaml config for this:

# Amazon Alexa via Emulated Hue
emulated_hue:
  type: alexa
  host_ip: 192.168.X.X
  listen_port: 80
  expose_by_default: false
  exposed_domains:
   - input_boolean
   - light
  entities:
   input_boolean.living_room_bluetooth:
    name: "Bluetooth 2"
    hidden: false
   input_boolean.living_room_tv:
    name: "TV 2"
    hidden: false
   light.office_ceiling_light_01_2:
    name: "Office Licht"
    hidden: false

Here the HELPER toggles:

And the the Emulated Hue is reachable via port 80:

But unfortunately the entities are not exposed and are not listed. Even if I try to search for new devices in the Alexa app.
In another post I saw that UpnP integration could help (I do not know why), but in my case with no luck.

I would be happy about any help

Thx in advance
