Vkontakte application. Page not loading in Iframe when using Laravel 4.1?

Question

Mobile development

Good day to all!
I haven't been able to find a solution to my problem for several days now. It is as follows:
There is a server with a signed certificate. I want to make an application for VKontakte through Iframe. If I create a page on the Laravel 4.1 framework, then the Iframe is empty. If I just put index.html in the root of the host, then the page is loaded. I don’t know where to dig anymore ... Maybe someone has come across a similar one? Stuck at the beginning...

what should be done?
Add to bootstrap/start.php

$app->forgetMiddleware('Illuminate\Http\FrameGuard');
