Hello I have socketio.exceptions.ConnectionError: OPEN packet not returned by server, and I cannot solve this problem
I just copy & paste, and them only modify apiKey to mine, Is there any regulation to operate this program? like operating time of server or OS or Socketio version?

@dokebivc try using socket.io version 2 instead of version 3. that should solve the issue.
