''noneType' object has no attribute is_ssl

Why do I constantly get this error and lose my connection !?

Hi. Could you provide some more info about this?

  1. Which websocket endpoint and stream did you try to connect?
  2. Did you use any library/ package?

I got the same problem.

  • wss://fstream.binance.com for User Data Streams.
  • was using binance_futures_python. I was just running the example of subscribeuserdata.py in example/user, and kept getting the error as Fendool saw.

Hi Everyone,

I managed to solve the problem by increasing the receive_limit_ms parameter when creating the SubscriptionClient:

sub_client = SubscriptionClient(api_key=g_api_key, secret_key=g_secret_key,
