Report Server with Azure Application Proxy

Hello,

We have followed the below to allow external access to our dashboards hosted on our report server.

Configure Power BI Report Server with Azure Application Proxy - Power BI | Microsoft Learn

Everything is working and we can see all the reports and download resources off it with no issue. However when you try and go into a report you just get an endless loading data screen. It doesn't error.

Anyone else had this issue and know the fix?

Cheers in advanced.
