Using https with socket.io 1.0.6 and getting an ERR_SSL_PROTOCOL_ERROR

I’ve been using https with socket.io on version 0.9 and below successfully for years. I went to upgrade to the new 1.0 version and I’m getting an SSL error. Here is the server-side node.js code to start the socket server:

var options = {};
options.key = fs.readFileSync('certs/ssh.key');
options.cert = fs.readFileSync('certs/cert.key'); //I've also tried using the property 'certificate' instead of 'cert'
var io = require('socket.io').listen(9091,options);

The connection works fine over standard http but https is giving me the error: ERR_SSL_PROTOCOL_ERROR

I know that all certificate file references are good. There seems to be no documentation on how to implement https socket.io connections on version 1.0, so I’m at a loss. Any help is much appreciated.

try binding to an http server first using express or the like using https, then attach Socket.IO to that.

var fs = require('fs');
var https = require('https');
var server = https.createServer({
  key: fs.readFileSync('key'),
  cert: fs.readFileSync('cert')
});

var eio = require('engine.io').attach(server);
var io = require('socket.io').listen(server);
