I am using Python 3.8.3
My program is a chat application using python-socketio with a redis queue using eventlet server in a docker container and load balanced with nginx
The program works fine on my local computer
But when I try to run in an an AWS EC2 linux instance, the pyfcm library when trying to send a Push Notification does not work and I get an ssl error.
I am using eventlet.monkeypatch(socket=True) at the start of the program
This is the error

My Program,
I have tried monkeypatching() before any other imports but then my websocket connections do not work as well as my databse connection times out. I have also tried the pyfcm import before and after the monkeypatch but nothing seems to work
import eventlet, socketio, save_history, pyfcm
from pyfcm import FCMNotification
eventlet.monkey_patch(socket= True)
#sio = socketio.Server()
mgr = socketio.RedisManager('redis://redis:PORT/0')
sio = socketio.Server(client_manager=mgr, async_mode='eventlet', logger=True)
app = socketio.WSGIApp(sio)
# Join Room when client comes online
@sio.on('subscribe')
def join_room_event(sid,data):
user = data['user_id']
channel = data['channel']
if save_history.check_user_channel(channel, user):
sio.enter_room(sid,channel)
sio.logger.log (level=20,msg="User " + str(user) + " in channel: " + str(channel) + " Joined and Verified with SID " + str(sid))
return True
else:
sio.logger.log (level=20,msg="User " + str(user) + " NOT in channel: " + str(channel) + " with SID " + str(sid))
return False
@sio.on('send_message')
def send_message_event(sid, data):
channel_id = data['channel']
user = data['user_id']
message = data['message']
if user and channel_id and message:
mid = save_history.save_message(channel_id, int(user), message)
data['message_id'] = mid['message_id']
data['time_sent'] = mid['time_sent']
sio.logger.log (level=20,msg='{Message: ' + message + ' with MID: ' +str(mid)+ ' sent by ' + str(user) + ' in channel ' + str(channel_id) + '}')
if mid['apns_result'] != 'no_apns':
push_service = FCMNotification(api_key='<api-key>')
result = push_service.notify_single_device(registration_id=mid['apns_result']['registration_id'], message_title=mid['apns_result']['message_title'], message_body=mid['apns_result']['message_body'])
sio.logger.log (level=20,msg=result)
sio.emit('receive_message', data, room=channel_id)
return data
else:
sio.emit('receive_message', { 'message' : "All params not present" } , room=channel_id)
return { 'message' : "All params not present" }
Any solutions will be greatly appreciated! Thank you

i had the same issue with python3.6, running pyfcm on python3.5 doesn't have this issue.
jerryz1982 commented
In python3.6 and eventlet > 0.17.4, this issue will happen.
eventlet/eventlet#371
jerryz1982 commented
Use eventlet.monkey_patch as early as possible in the code fixed the issue.

Using the eventlet wrapper for SSL protocols and upgrading to version 0.26 worked for me for all libraries
