Python 3.6: [WinError 10054] OR sslv3 alert bad record mac

[kotvrt]

Hello,

I'm using python 3.6 and I'm trying to connect to 2.x socket. The lib is socketIO-client-nexus 0.7.5. Here's the code:

def on_response(*args):
    print('response: ', args)

with SocketIO('https://streamer.cryptocompare.com', 443, LoggingNamespace) as socket:
    socket.on('on_response', on_response)
    socket.send("['0~Poloniex~BTC~USD']")
    socket.wait(seconds=10)

I managed to connect to this websocket on only one occassion and I got the expected response.

As soon as I quit the program and tried reconnecting later on - I encounter one of the following two scenarios:

First - WinError 10054

If I try relaunching the program however, it appears that I manage to connect, following warning pops up only before the connection is closed:

WARNING:socketIO-client:streamer.cryptocompare.com:443/socket.io [connection error] recv disconnected by SSL ([SSL: SSLV3_ALERT_BAD_RECORD_MAC] sslv3 alert bad record mac (_ssl.c:2171))

Am I doing something wrong?

Hey guys, any updates on this issue? My colleague experiences similar problem.

@rassokhin-s I don't think they made some progress about it otherwise I guess the issue would have been updated. I abandonded the python library and ended up creating a small program in node.js to exploit the API...

@kotvrt thanks for reply!
