socketioDAT does not connect to public https url

#build 2020.24520 on Windows 10 Pro

SocketIO connects to http server but not https. Testing with the official socket.io chat example: https://socketio-chat-h9jt.herokuapp.com/ found here: https://socket.io/demos/chat/

This is the output from the touch text console when connecting to the https url:

[2020-06-26 14:20:37] [connect] Successful connection
[2020-06-26 14:20:37] [error] handle_read_http_response error: websocketpp.transport:7 (End of File)
[2020-06-26 14:20:37] [info] asio async_shutdown error: system:10054 (An existing connection was forcibly closed by the remote host)
