Websocket error #13

robozb · 2024-12-11T08:44:17Z

Dear Dev,

I got this error message on my Linux. I'd like to test the socket, please send me the API URL.

hi @robozb what version of the lib are you using ?

robozb · 2024-12-11T09:03:03Z

I guess the latest:

  <dependency>
      <groupId>com.github.realzimboguy.ewelink.api</groupId>
      <artifactId>ewelink-api-java</artifactId>
      <version>3.3.3-RELEASE</version>
  </dependency>

RealZimboGuy · 2024-12-11T09:04:15Z

the logins go to

      baseUrl = "https://"+region+"-apia.coolkit.cc/v2/";

the websockets go to

      "wss://"+ region+"-pconnect3.coolkit.cc:8080/api/ws"

region comes from what you init the api ie "eu"

robozb · 2024-12-11T09:05:50Z

It is interesting, all things works well in Win10, but not on my Linux RPI4 on the same network.
The other network traffic works well as well on Linux. I created a jar-with-deps, all good with Win10 but not on Linux.

On Linux with almost the same JDK (Oracle 17) I got this errors all the time:

Thank you so much! I check it out :)

RealZimboGuy · 2024-12-11T09:07:32Z

are you doing eweLink.getWebSocket(new WssResponse() {

there has been some issues with trying to turn on/off a device too fast from init. slower things like PI might not have fully setup the websocket connection yet

robozb · 2024-12-11T09:09:47Z

I guess this is the code block where the exception arised:

    void lampaKapcsolasa(Lampa lampa, Kapcsolas kapcsolas) {
        if(MOTION_ERTESITES)
            detectionPause();
        try {
            logger.info(String.format(
                "lampaKapcsolasa... %s %s",
                lampa.name(),
                kapcsolas.name()));
            eweLink.setDeviceStatus(lampa.deviceID,kapcsolas.name());
        } catch (Throwable kivetel) {
            logger.error("Problemas lampa: "+lampa.name()+"->"+lampa.deviceID+"->"+kapcsolas.name(),kivetel);
        }        
        if(MOTION_ERTESITES)
            detectionStart();
    }

Sorry for the hungarian language :)

RealZimboGuy · 2024-12-11T09:11:13Z

is

EweLink eweLink

declared as a static instance or only created once ?

robozb · 2024-12-11T09:11:29Z

I'd like to test the API urls to make sure the error not in my code.

RealZimboGuy · 2024-12-11T09:13:12Z

we had issues here #9

where if you did not create the websocket listener it was giving the same error but that should be fixed now

RealZimboGuy · 2024-12-11T09:14:54Z

can you enable log level debug on

code looks ok, try to check network

  telnet    eu-apia.coolkit.cc 443
  
  telnet   eu-pconnect3.coolkit.cc 8080

then next to check if server SSL CA certificates ok

  curl -v https://eu-apia.coolkit.cc/v2/user/login
  
  npm install -g wscat
  wscat -c wss://eu-pconnect3.coolkit.cc:8080/api/ws

RealZimboGuy · 2024-12-11T09:26:44Z

curl should return {"error":403,"msg":"api not found","data":{}}%

and wscat should show

So it seems the connection was successful

RealZimboGuy · 2024-12-11T09:42:08Z

a bit of a guess, can you try with another JRE ie

https://docs.aws.amazon.com/corretto/latest/corretto-17-ug/downloads-list.html

robozb · 2024-12-11T09:43:46Z

The wscat output:

Thanks for your help! I will give a feedback about the solution (if it is possible :) )
