Failed to pair! Make sure TV is online and you click "Allow" on the popup

[scsh4]

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.

Hi @scsh4,

As you can see the plugin tries 3 times to pair the TV but it can't reach it.

This means that the machine you are runing homebridge on can't access the TV.

• Make sure the IP is correct in the config file.
• From the server you are running homebridge try to run ping 192.168.86.43 and see if it can reach the TV.

And indeed, your TV is supported.

I am able to ping the TV at the address specified above:

I am also accessing the REST interface via the same machine, for which I posted the response above.

Also, an ICMP response directly from the Homebridge Terminal.

Try to hard restart your TV by holding the power button pressed until the Samsung logo appears.

Maybe your router blocking connections? Blocked ports from docker? Try to run it with network_mode: host

[scsh4]

I have other plugins installed (FFmpeg, Homebridge Printer, etc.) installed for local devices and they work fine. For the sake of troubleshooting, I disabled all firewalls and ensured that host mode is active. I hard restarted my TV but still get the same error.

I'm sorry but I don't know what else to recommend you. Something is blocking the connection because the server can't reach the TV on that IP address ...
