.NET version for Power BI Report Server May 2023

tamiribas — Mon, 04 Aug 2025 07:43:12 GMT

What is the .NET version that supported Power BI Report Server May 2023?

I am trying to understand if an update of .NET to 4.8 is the reason for the reports refresh problems (in Import Mode)

Thank you,

Tamir

Hi tamiribas,

Thank you for reaching out to the Microsoft Fabric Forum Community.

.NET Framework 4.8 is officially supported and required for Power BI Report Server, so upgrading should not typically cause issues. If you are seeing data refresh failures in Import Mode after updating .NET, the problem may be related to your server configuration. Check the Report Server logs and Windows Event Viewer for errors, and please provide a screenshot of the specific error message for further troubleshooting.

The problems with the refresh began after a server update and an update of .NET 4.8.

I asked my customer to roll back, but it did not resolve the problem.

1. Reports that had a scheduled refresh before the updates are still running successfully.

2. New reports are failing to run a successful scheduled refresh

3. Same report (!) has a successful scheduled refresh, but when setting up a new scheduled refresh...it fails

4. a manual refresh for the same report works fine

Any idea?

It is not allowed to send a log dure to information security

Thank you,

Tamir

Hi tamiribas,

As the issue is still not resolved, I recommend raising a Microsoft Support ticket so that one of our backend engineers can help investigate and resolve it. You can raise a support request here:
