Client network socket disconnected before secure TLS connection was established

[joroMaser]

I removed my Dlink from mydlink app , then I add back only to wifi then I closed the application

I have tried to run:
node switch.js 192.168.1.11 <PIN_CODE> 1 0

And I got

Signed in!                                                                                                                 
Getting state                                                   
Had error: { Error: API Error 2: system error                    
    at WebSocketClient._getSetting (/mnt/dlink_websocketclient/index.js:282:27)   
    at process._tickCallback (internal/process/next_tick.js:68:7) code: 2 }

What does it mean please?

If I make a wrong with PIN code I got:

Signed in!

Hi,

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

@Garfonso I have edit my post , thank you

@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.

@Garfonso
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.

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

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