After having the webos integration running fine for over 2 years it became flaky over the last few weeks and has now completely stopped working.
The main reason is that the integration doesn’t detect the TV anymore (an older model running on 1.4.0).
I remove the original pairing and tried to re-pair the device. The logs show a very clear:
[homeassistant.components.webostv] Unable to connect to host 192.168.1.104
Now, the device IS running on that ip, I’ve confirmed that both in the TV network settings and in my router. Also I can ping the host from my home assistent container.
I did some more digging and found that the port the library uses does not respond to telnet commands.
telnet 192.168.1.104 3000
Trying 192.168.1.104...
telnet: Unable to connect to remote host: Connection refused
After running nmap as well it shows only one port is opened: 9998
nmap 192.168.1.104
Starting Nmap 7.60 ( https://nmap.org ) at 2020-10-31 08:25 CET
Nmap scan report for 192.168.1.104
Host is up (0.0052s latency).
Not shown: 999 closed ports
PORT STATE SERVICE
9998/tcp open distinct32
Nmap done: 1 IP address (1 host up) scanned in 0.13 seconds
That is as far as I got and am a bit out of ideas… Does anyone have any more suggestions to either debug this, or even fix it?
