PBIRS Sep. 2026 using excel as datasource
PBIRS Sep 2026 has been released and the change log shows "Setup no longer installs the Microsoft Access Database Engine. To use Access or Excel data sources, install the Access Database Engine on the report server". Is there any documentation or SOP tell us about which version of Access Database Engine to install? or I have to install it from M365 Office installer?
Power BI Report Server Scale-Out Issue - Reports Visible from One Node but Empty Folder from Another
Hi Folks I am experiencing a weird issue on newly built servers where I have migrated the report server databases from SQL 2017 to SQL 2025 and Powerb Report server (May 2026) is installed in a scale out deployment on the same SQL AG nodes. Environment Power BI Report Server (Native Mode) 2-node scale-out deployment ReportServer database hosted on a SQL Server Always On Availability Group Access through a cluster/network name (virtual hostname) HTTPS configured using a new SSL certificate Both PBIRS nodes point to the same ReportServer database The PBIRS web portal loads successfully on both nodes. Authentication succeeds. However, it always displays "This folder is empty message" when webportal is accessesed from primary replica node. When requests are served by Node B, All reports and folders are displayed correctly. The behavior appears to follow the active hosting node rather than the user account. Has anyone come across this issue or have a clue on what is going on? Thanks in advance.

Failed to connect to AS
I currently have a server running PBIRS Version 1.25.9558.32914 (January 2026), and I'm experiencing this type of error on several dashboards during automatic refreshes. " Failed to connect to AS " What could be the problem? The server resources aren't overloaded, as I've monitored the CPU and RAM usage during these refreshes. What can I check, given that this is happening so frequently?
