@Master79 ,
This is the applications control channel. may not be significant. does yout TV give an access code when an app tries to connect? if so, it uses encrypted websockets, and the binding doesn’t support that.
If it just asks to allow the connection, then it should be OK. TV’s from 2015/2016 are dodgy though because this is when Samsung was doing the encrypted websocket thing.
I have posted an updated binding - try that, and post the log so I can see what is happening.
