Client network socket disconnected before secure TLS connection was established about dlinkwebsocketclient HOT 5 CLOSED

Hi,

what device do you try to talk to?
Do you see a webpage on the IP?

from dlinkwebsocketclient.

@Garfonso I have edit my post , thank you

from dlinkwebsocketclient.

@joroMaser what device do you want to talk to? DSP-W118?

The device returns an error, when the library asks for the current state of the socket.
You can try with a modified version of the switch.js file (which is meant as example anyway) and remove the client.state() call and see if it manages to switch the socket on or off.

Do you mean comment out the lines:

let state = await client.state();
console.log('Socket is ' + (state ? 'on' : 'off'));

in switch.js ?

I still got

Had error: Error: API Error 2: system error   
    at WebSocketClient._setSetting (/mnt/dlink_websocketclient/index.js:263:19)       
    at process._tickCallback (internal/process/next_tick.js:68:7

yes.

So it can not switch.
What device is this? (third time I ask... sorry.... without this information I can recommend nothing further)
