Web Browse PDF Reader

Hello,

My customer is using the web browser component to access their reporting website.
As you can see in the image 11, everything else shows in the web browser component except actual reports (image 22). We did confirm that this report does load when we just use a web browser like chrome or IE outside of Ignition.

Why are we not able to load reports from the web browser component? Does it have to do with the PDF viewer on this website?
