SSL connection Issue

[fred-dev]

I have been testing a few different websocket servers and some functionality with this addon. I can connect to external servers as long as they don't use SSL.
For example connecting with a client like so:
client.connect("wss://echo.websocket.org", true);
results in:
[1585755136:2758] ERR: server's cert didn't look good, X509_V_ERR = 20: error:00000014:lib(0):func(0):SSL lib

I am actually trying to connect to connect with Websocket.IN, I am not sure if the errors are related.
Websocket.IN have a test server - here
If I try enter the test server (I think these get regenerated so the demo API key may be expired)
but calling:

client.connect("wss://connect.websocket.in/v3/1?apiKey=oCdCMcMPQpbvNjUIzqtvF1d2X2okWpDQj4AwARJuAgtjhzKxVEjQU6IdCjwm", true);

I just get client connection failed
