Error Can't connect to the server in Subscribe methode

[luke313]

@JKorf First of all thank you for creating this library.

In my app I create a socketClient to receive data from Binance. All methods were working, but when I use the Subscribe method, I get this error message: "Can't connect to the server".

I am running the latest version of nuget.
in .netframework 4.7.2

code:
var result = await socketClient.SpotApi.ExchangeData.SubscribeToTickerUpdatesAsync("FTMUSDT", data => { label1.Text = data.Data.LastPrice.ToString(); });
