Hi @Simonawu ,

Thank you for reaching out to the Microsoft Community Forum.

This is a known behavior in Power BI Report Server (PBIRS) when permissions are not properly configured after an upgrade or fresh installation.

PBIRS uses Windows Authentication either NTLM or Kerberos for user access. If the user accessing the portal does not have permissions, not added as a PBIRS admin or to a security role, the server tries to authenticate repeatedly, causing the refresh loop. This is common after upgrades because previous permissions might not carry over correctly.

Please try below things to fix the issue.

1. Log in with an account that is a PBIRS Administrator.

2. Go to Site Settings --> Security and add the required domain users or groups.

3. Assign them roles like System Administrator or Content Manager as needed.

If You Cannot Log In, Use Report Server Configuration Manager:

1. Go to Web Portal URL and ensure it’s accessible.

2. If you still can’t log in, use SQL Server Management Studio (SSMS): Connect to the PBIRS database (ReportServer). Run below query to add an admin:

INSERT INTO [ReportServer].[dbo].[Users](UserName, SID, AuthType)

Then assign roles in the PolicyUserRole table.

Cross-Version Upgrade: Upgrading from Jan 2025 (202501) to Sep 2025 (202509) should not break authentication, but it may reset permissions if the database was reconfigured. Always back up the ReportServer database and RSReportServer.config before upgrading.

I hope this information helps. Please do let us know if you have any further queries.

Regards,

Dinesh

Yes, I saw your post. My version was upgraded from 202501 to 202509. I'm not sure if it has something to do with cross-version upgrading.

Hi @Simonawu, 

I have September 2025 installed and am not encounting this issue. 

Are you using Kerberos auth or NTLM? Are your SPNs all valid? 

If you found this helpful, consider giving some Kudos. If I answered your question or solved your problem, mark this post as the solution.

Thanks for your reply. but I don't know how to determine whether we are using Kerberos auth or NTLM. Here are some information I have looked up.

Service Account: PBIRS is running under the NT SERVICE\PowerBIReportServer virtual account.

End Users: Access the PBIRS portal using their individual domain credentials (DOMAIN\username) from their workstations.
