Which frame TV are you using? Are you sure you are adding the right TV and the docker container can connect to the TV? You could test by pinging the TV IP from the docker terminal :)

[mrtncode]

And have you checked if there was a popup to confirm on the TV? If yes ans you didnt confirm the access on the TV, that can cause the connection timeout. In this case I should add better error handling for this.

[johntdyer]

The TV is a QN50LS03BAFXZA frame tv

ICMP works from the docker host

PING 192.168.120.178 (192.168.120.178) 56(84) bytes of data.
64 bytes from 192.168.120.178: icmp_seq=1 ttl=63 time=0.346 ms
64 bytes from 192.168.120.178: icmp_seq=2 ttl=63 time=0.317 ms
^C

I also tested several ports from within the container and they can connect

root@5311e963a14c:/app# nc -z 192.168.120.178 8001
Connection to 192.168.120.178 8001 port [tcp/*] succeeded!

Okay thanks. Do you see a popup on the TV when adding it to the frametv-gallery? Usually you have to confirm this popup and then it should connect.

[mrtncode]

You should also make sure that the TV is on and check your TV settings. It might be that your TV has some settings disabled that block connections to the TV :)

[johntdyer]

yes, there is no popup on the tv

@johntdyer Did you upgrade your firmware in the last time? There are some reports in the underlying library samsungtvws: xchwarze/samsung-tv-ws-api#184 where a User describes a similar problem. It could that Samsung broke the WS API to force using SmartThings :(

If this is the case, maybe you‘d like to reach out the samsung support. It would be very interesting if Samsung really broke the local WS API.

[mrtncode]

You could try to go to the TV‘s settings -> Connection -> External device management -> Device connection manager and see if there are any devices/ requests
