Sending packet PING data None Unexpected error "timed out", closing connection

[sayyep]

Hi!

• I have an issue and I cannot resolve it, please help me
• Overview: I have 2 services. 1 is call_service and 2 is socker_service and they connect together via the message queue of Redis
• Here is my code:

1. apps.socket.views.py:
   sio = socketio.Server(async_mode='eventlet', cors_allowed_origins='*', logger=True, engineio_logger=True)

2. wsgi.py:

import os
from threading import Thread

import eventlet.wsgi
import socketio
from common_modules.core.redis import RedisConnection
from common_modules.utils.channel import WAIT_ACTION
from django.core.wsgi import get_wsgi_application

from apps.socket.views import sio
from services.socket import SocketService

os.environ.setdefault('DJANGO_SETTINGS_MODULE', 'socket_service.settings')

application = get_wsgi_application()
application = socketio.WSGIApp(sio, application)

def start_subscribe_message():
    def run():
        socket_service = SocketService()
        redis_queue = RedisConnection().established_connection()
        pubsub = redis_queue.pubsub()
        queues = [WAIT_ACTION]
        for queue in queues:
            pubsub.subscribe(queue)
            for message in pubsub.listen():
                if message:
                    channel = message.get('channel', '')
                    if channel.decode("utf-8") == WAIT_ACTION:
                        data = message.get('data', '')
                        print(data)
                        if data != 1:
                            data = data.decode('utf-8').replace("'", '"')
                            print("sio wait: " + str(id(sio)))
                            sio.emit(event='wait-action', data="PONG wait")
    thread = Thread(target=run)
    thread.start()
start_subscribe_message()
eventlet.wsgi.server(eventlet.listen(('', 8400)), application)

• Issue:
  When I publish a message to Redis with channel WAIT_ACTION, the Redis queue still receives this message. But when I want to emit data to the Client with channel wait-action, the program run to the line sio.emit(event='wait-action', data="PONG wait"). It logs for me like that:
  emitting event "wait-action" to all [/]
