Portlet don't work on an online server and It doesn't show the error

Good afternoon, everyone.

I deployed my portlet to a online server today and it’s not working. It keeps loading something and then stops and shows nothing. I really don’t know what to do in this situation. I’m using the version 7.1.15 of vaadin and vaadin is fully integrated with liferay at the online glassfish.

At localhost It work fine.

In the attachment there is a image that show what the firebug console catch in the end of the loading.

Check the servers log
