I was having that trouble, finally the solution was to put a valid Callback url in my twitter API at (https://dev.twitter.com/‎), I used google+ url, saved changes (it could take a minutes before the changes are made, refresh the page to be sure) and it worked.

Yes, your authentication is not working because Twitter made some recent changes regarding how it lets 3rd party code authenticate.

In other words, Basic authentication has been turned off for the API.

As Allain mentions, oAuth is the way to go.

The code you posted is different than what I've seen in the past for connecting. I think (though I'm not sure) that oAuth is the preferred way of authenticating now.

Here's a blog that details using oAuth to connect.
