WebSocket is disconnecting after 2 mins

[sathish-valleru-19]

Hi,

1. Launching the app the websocket connection was successful.
2. keep app idle for 2 min webscoket is disconnected automatically and giving below error WebSocketFrame(FIN=1,RSV1=0,RSV2=0,RSV3=0,Opcode=CLOSE,Length=42,CloseCode=1002,Reason="No more WebSocket frame from the server.")
3. After socket is disconnected, how to connect socket again without killing the app

Websocket client connection logic:

try {

        if (webSocket == null) {
            webSocket = new WebSocketFactory().createSocket(endPoint);
            webSocket.addHeader("Authorization", idToken);
            webSocket.setPingInterval(600000);
            webSocket.addListener(webSocketAdapter);
            Log.i(TAG, "ws.connectAsynchronously () is null =" + webSocket.toString());
        } else {
            webSocket = webSocket.recreate();
            Log.i(TAG, "ws.connectAsynchronously () is not null =" + webSocket.toString());
        }
        webSocket.connectAsynchronously();
    } catch (IOException e) {
        e.printStackTrace();
    }

Need help to resolve this.

Same error. I'm catching the onDisconnected event:

 @Override
  public void onDisconnected(WebSocket websocket,
   WebSocketFrame serverCloseFrame,
   WebSocketFrame clientCloseFrame,
   boolean closedByServer) {
     reconnect();
 }

And the parameter closedByServer is always false. I've not set any ping interval. What can be the reason?

This is usually a server-side problem; e.g. if your webserver is behind an nginx reverse proxy (e.g. kubernetes ingress), the default parameters make it disconnect in 2 minutes.

Hi,

I also get the onDisconnected notification with the reason: CloseCode=1002,Reason="No more WebSocket frame from the server

In my case, I receive the same data from the same source with different WebSocket sessions (on different hosts). But some of them sometimes gives above onDisconnected case.

As seen below, Session 1 does not get any data after 13:25:17 and onDisconnected is called after 79 seconds. But Session 2 gets data and has no problem.

Websocket client connection logic is:

            webSocket = websocketFactory
                    .createSocket(url)
                    .addProtocol("tr_json2")
                    .addListener(this)
                    .addExtension(WebSocketExtension.PERMESSAGE_DEFLATE);

You could try sending pings and enable pongs on your server. This fixed the issue for me. Use the Websocket#setPingInterval method for this.

webSocket = websocketFactory
                    .createSocket(url)
                    .addProtocol("tr_json2")
                    .addListener(this).setPingInterval(pingDuration)
                    .addExtension(WebSocketExtension.PERMESSAGE_DEFLATE);
