socket.IO-objc example returns server code 400

I'm using the default example provided in the https://github.com/pkyeck/socket.IO-objc GitHub repo. And SocketIO throws an error that the handshake failed and the server returned with status code 400. I have successfully connected to the server with the socket.io Javascript library.

- (void) viewDidLoad
{
    [super viewDidLoad];
    socketIO = [[SocketIO alloc] initWithDelegate:self];
    socketIO.useSecure = YES;

    [socketIO connectToHost:@"[url]" onPort:443];
}

I also had such error when hard-coded my Mac's IP into iOS app code. Once I have dynamic IP, one day it has been changed and - pfff - handshake error and timeout.

Check the version number, guess you are using version 0.9, your server side code using version 1.0. Both server and client should be in same version.
