Hi, I developed simple project with flask soket io and try to get real time voice in backend. in localhost it works and receive data but when i run it in remote server it doesn`t work.

@socketio.on('write-audio')
def write_audio(data):
    """Write a chunk of audio from the client."""
    print(type(data))
  

@socketio.on('connect')
def on_connect():
    print('on_connect')
    socketio.start_background_task(target=target_class.background_thread_from_stream, app=current_app._get_current_object())

socket.on('connect', function() {
    console.log('CONNECTION ESTABLISHED !!')
});
soket.emit('write-audio', buffer)

It's really impossible for me to tell you what's wrong, but my guess is that this is a problem with how you deployed your application. Have you read the documentation, specifically the section that describes deployment options? I would suggest you start from there.
