[You are requesting vast xml for zone which does not apear to be a video overlay banner nor a vast inline banner]

Good afternoon.

Saw here on the forum link
URL/www/delivery/fc.php?script=bannerTypeHtml:vastInlineBannerTypeHtml:vastInlineHtml&format=vast&nz=1&zones=pre-roll%3DidZone

Thank you.

But when the link is called for the first time, there is no content.
There is only an option: 

----------

<!-- You are requesting vast xml for zone  which does not apear to be a video overlay banner nor a vast inline banner. 
-->

----------

If the browser refreshes the page, then hm content appears.

How do I make the content right when I request it for the first time?

I added two video banners (Inline Video Ad (pre / mid / post-roll))
