Current behaviour

While trying to check your online examples I saw that none of them is functional. Whether is a known issue or not I considered a good idea to inform you. The error receiving is:

XMLHttpRequest cannot load http://slack.socket.io/socket.io/?EIO=3&transport=polling&t=LVuf8-O. No 'Access-Control-Allow-Origin' header is present on the requested resource. Origin 'http://socket.io' is therefore not allowed access. The response had HTTP status code 502.

Setup

• OS: Ubuntu 16.04
• browser: chrome
• socket.io version:

Had some headaches with the middleware for authentication, all the examples say to migrate to this:

io.use(function(socket, next) {
  var handshakeData = socket.request;
  next();
});

But there I found it to be more like this:

io.use(function(socket, next) {
  var handshakeData = socket.handshake;
  next();
});

That should be fixed now, thanks.
