socket.io client always closing

[Notadumdum]

hey i tried making this connection work... i first installed the updated version of python-socketio[client]==5.7.1 but apparently this version supports EIO=4 and the socket.io client i'm trying to open is EIO=3.. so i had to uninstall it and install an old version python-socketio==4.6.1 . after that i tried running this code

import socketio

sio = socketio.Client(ssl_verify=False,logger=True,engineio_logger=True)

@sio.event
def connect():
    print("Connected!")
    sio.emit("authorization",{"session":"2ot3i7..................3h","isDemo":1})

@sio.event
def connect_error(data):
    print("The connection failed!\n\n" + data)

@sio.event
def disconnect():
    print("Disconnected!")


@sio.on('*')
def catch_all(event,data):
    pass



@sio.on('handshake')
def on_message(data):
    print('Handshake',data)
    sio.emit("instruments/update",{"asset":"GBPUSD","period":60})
    sio.emit("indicator/list")
    sio.emit("drawing/load")
    sio.emit("pending/list")
    sio.emit("chart_notification/get")
    sio.emit("depth/follow","GBPUSD")
    sio.emit("tick")
    sio.emit("settings/store",{"chartId":"graph","settings":{"chartId":"graph","chartType":2,"currentExpirationTime":0,"isFastOption":False,"isFastAmountOption":False,"isIndicatorsMinimized":False,"isIndicatorsShowing":True,"isShortBetElement":False,"chartPeriod":4,"currentAsset":{"symbol":"GBPUSD"},"dealValue":1000,"dealPercentValue":1,"isVisible":True,"timePeriod":60,"gridOpacity":8,"isAutoScrolling":1,"isOneClickTrade":True,"upColor":"#0FAF59","downColor":"#FF6251"}})
if __name__ == '__main__' :
    sio.connect('https://ws.domain.io/socket.io/', transports=['websocket'])
    sio.wait()

and here is what came back...

i had to kill the terminal cause it was trying to reconnect

please if you have any questions to make my explanations clear you can comment and i'll answer thank you if you can give an advice

The log does not show anything abnormal. It seems the server disconnected you after you sent your authorization details.

Hey Miguel Grinberg.. yesterday I was looking through this website's certificate and I saw a part that says
EXTENDED KEY USAGES----(Purposes): Server Authentication,Client Authentication
So the question is do you think the connection I'm trying to authenticate needs the ssl certificate for it to work

[miguelgrinberg]

I think you may be confusing user authentication with SSL certificate validation and encryption, which are completely different things. SSL certificates are not handled by this library at all, this is something that is handled between the HTTP client and the web server. So I really don't know how to answer your question, to me it seems completely unrelated to the topic of Socket.IO.

Ok

Have you ever received any complaints as close to mine and the person has fixed it.. if so can you please send a link or something.. I'm really clueless

[miguelgrinberg]

I mentioned this a few times already. The logs that you shared do not suggest there are any issues. You are passing some sort of token to the server right after you connect:

sio.emit("authorization",{"session":"2ot3i7..................3h","isDemo":1})

The server does not appear to like it and is ending the connection after this.

The most likely issue here is that this session value that you are passing is not being accepted by the server.
