UE55H6600SV does not show up in log

[stotz89]

Hi,
I have added my TV in the config.json via

{
            "platform": "SamsungTVControl",
            "devices": [
                {
                    "usn": "uuid:068e7781-006e-1000-bbbf-xxxxxxxxx",
                    "name": "Samsung TV"
                }
            ]
        },

The usn I found out via postman http://<my_ip>:8001/api/v2/

The command npx homebridge-samsungtv-control pair1 <myip> <mymac> requires then a PIN which is shown on my TV screen. After entering the PIN in the command line and click enter, it works successfully and my TV is muted. When I try npx homebridge-samsungtv-control discover I get the following:

Searching for devices...
Got error while trying to check device with usn: "uuid:0c845881-00d2-1000-8d3a-505xxxxxxxx". HTTPError: Response code 401 (Unauthorised)
    at EventEmitter.<anonymous> (/homebridge/node_modules/homebridge-samsungtv-control/node_modules/got/dist/source/as-promise.js:118:31)
    at processTicksAndRejections (internal/process/task_queues.js:97:5)
😞 No Samsung TV found. Remember to turn on your Samsung TV's and check if they are connected to the same network before starting the discovery.

During the the startup I also can't see that any TV is initialised. I also can't see anything in my home app. Am I doing something wrong? Do I miss something?
My homebridge is running inside a docker container. Is this maybe an issue?

Thanks for your help!!
