I cannot connect to wss://stream.data.alpaca.markets/v2/sip
I have no problem connecting to wss://data.alpaca.markets/stream or any other websocket server i tried including Polygon, TD Ameritrade, and many others.
I’m using fully patched Windows 2012 R2 server running .Net 4.8 app. It appears that windows 202 R2 does not support TLS1.3 I’m not an expert in SSL but based on my Wireshark research I get a connection failure because my client is using TLS1.2 ciphers while your server requires min ver 1.3
If i’m right what is the possible reason for limiting your connection to TLS1.3 clients only?
If i’m wrong please advise on what can possibly be the cause of such failures (see image below)
