Not receiving any websocket packets

I don't seem to receive any packets from the WS using the above implementation. The verification does not throw so presumably the connection is live. Any thoughts?

please use lower case symbol. btcusdt

This throws the exception Binance.Common.BinanceClientException: 'Illegal characters found in parameter 'symbol'; legal range is '^[A-Z0-9-_.]{1,20}$'.'.

Okay, fixed the above issue. Seems like the http client requires an uppercase symbol, and the ws client requires a lowercase symbol which is odd. Can mark as closed.
