Failed to pair! Make sure TV is online and you click "Allow" on the popup
I know this issue, for some, is related to an old version of Tizen, but I don't think that's my issue. I am running Homebridge v1.4.1 on Docker. Installed Homebridge Samsung Tizen v5.2.3 plugin, configuring it as follows:

```
{
    "devices": [
        {
            "name": "Samsung QN85AA 85 TV",
            "ip": "192.168.86.43",
            "mac": "80:47:86:d6:66:9c",
            "inputs": [
                {
                    "type": "app"
                }
            ]
        }
    ],
    "platform": "SamsungTizen"
}
```

My QN85A is a 2021 model running Tizen version 1904. I can access the API via the TV's IP address which returns the following response:

Despite all of that, I receive the following error in Homebridge:

There is never a popup to click "Allow" on.
