How can I make Clay.io plugin work online?

I made a little game and uploaded to dropbox. It works fine but I can't login or post scoreboard.
I assume Clay.io plugin can't connect to the internet, but in preview I don't get this problem.

Any suggestion?

Thanks

just a thought, as I lost my magic 8-ball to look into your code: Have you disabled debug-mode of the clay.io plugin before you exported your project to HTML5?

Yes, I disabled it.
Still don't works
This is the dropbox link:
https://dl.dropboxusercontent.com/u/185 ... index.html

EDIT: I went in my Clay.io dashboard and I:
-went to "Settings" and copied my dropbox game link into "Path to game" section.
-went to"Distribute>Any Website" and i copied the html code and put it in my website code
-opened my website the scoreboard and the login worked!

Clay.io still not working properly from direct dropbox link.
