Power BI Report Server not Rendering reports. .Net error

[DKHUghes55]

Hi Fabric Community,

I have an issue with our Power BI Report Server instance.  We are running September 2023 currently.

The error the users see is Service Unavailable, HTTP 503.

What I see on the server is 

Application: ReportingServicesService.exe
Framework Version: v4.0.30319
Description: The process was terminated due to an internal error in the .NET Runtime at IP 00007FFD86433714 (00007FFD86410000) with exit code 80131506.

I have tried a Repair operation to correct the issue then rebooted the server.  It worked for about 2 days then the error returned.

This has my site down at the moment.  Any suggestions?

Thanks,

DKHughes55

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:

There may be an issue with SSL certificate binding. Updating the web service URL and web portal URL in Reporting Services Configuration Manager can be helpful to others. You can check the following post:

Verify that the service account running the Power BI Report Server service is the same as the one configured in Report Server Configuration Manager.

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.

Hi v-yohua-msft,

There were a couple of things causing the issue.  One of them was the cert binding on the web service URL.  The other issue was the server was patched/updated on Sunday night and there was a microsoft installer stalled on a few .Net modules.  All is well now.  

Thank you for the help.  

I will mark this as an accepted solution.

Hi Fabric Community

Another piece of the puzzle. The Service Unavailable issue is only with the pagenated reports.  The Power BI Reports work fine on the server.

Thanks,
