Integrating Vaadin 8 Application in Sharepoint - Not Working on IE

I’m trying to integrate my Vaadin 8 Application in Sharepoint.

  1. In Sharepoint, I added a Webpart. In it I have an iframe. In this iframe I loaded my vaadin 8 app.
    <iframe src="vaadin8app">

It is working fine on all the browsers except on Internet Explorer. It keeps on loading on IE.
I tried to change the meta tag but it didn’t work.
Any one have any idea how to resolve this issue?
