I use QuantConnect and few days ago I noticed it can’t connect to alpaca websocket with an error like:
An error has occurred during a TLS handshake. —> System.Security.Authenticati
on.AuthenticationException: A call to SSPI failed, see inner exception. —> Sys
tem.ComponentModel.Win32Exception: The message received was unexpected or badly
I wonder if there has been some changes made to the websocket server, since this code was working 2 weeks ago.
