socket.io-client.cpp does not connect to node app on Heroku while Node JS socket.io-client does without any problem. Error is:

Changed URL from https to http://myapp.heroku.com - works now. Is it possible to connect via https as well? JS socket.io-client connects via secure connection without any problem.
Have built socket.io-client-cpp app with SIO_TLS in DEFINES (compiler flag: -DSIO_TLS) - connects via https fine now! This enables TLS support as mentioned here:
