Client not ping & disconnect after 10 seconds

overbost commented 3 years ago

EDIT: gevent-websocket (enabling server websockets) partially resolve the issue. The client remain connected with ping/pong but "connect" event is fired twice. Polling transport option not work, like other options...

My socket.io server is a Flask application with this packages installed:

python-engineio 3.14.2
python-socketio 4.6.1
Flask-SocketIO 4.3.2 My Flask app work fine with socket.io-client (browser version)

This is what append:

The app connect the server
The app receive twice "connect" event, one with "undefined" data and the second with correct data
The app doesn't ping the server (like waiting for server ping?!)
After 10 seconds app send a disconnection event
All emits works fine, but app can't maintain the connection

this is the flask log with client disconnection :

WebSocket transport not available. Install eventlet or gevent and gevent-websocket for improved performance.

This is the app log event

JS: connected
JS: undefined
JS: connected
JS: connect
JS: error
JS: null
JS: disconnected
JS: transport error
JS: connected
JS: undefined
JS: connected
JS: connect

Is there any code involved?

The app is really basic:

        const socket = new SocketIO('http://192.168.1.110:5000?platform=android');

        socket.on("connect", (data)=>{
          console.log("connected")
          console.log(data)
        })
        socket.on("disconnect", (data)=>{
          console.log("disconnected")
          console.log(data)
        })

        socket.on("error", (data)=>{
          console.log("error")
          console.log(data)
        })

        socket.connect()
