Power BI Report Server not Rendering reports. .Net error

Hi, DKHUghes55 

Ensure that the report server's application pool is running. Sometimes, the application pool may stop, resulting in a 503 error. Make sure you have the latest version of the .NET Framework installed. Some users have solved similar issues by updating to the latest version. You can refer to the following post:

Hi Fabric Community,

We found the issue.  There was a setting in th McAfee configuration that was blocking some .Net operations.  This was the setting: AMSI unchecked policy.

This has been resolved.
