Data refresh error
Hi WithwindOK ,
Please try the troubleshooting steps, which i was suggested in my previous response. In addition to that, Colud you please try the below steps to fix the issue.
1. Please check the RSPortal, RSService, and AS logs at the time of the failure. check for memory pressure, timeouts, or model loading errors.
2. Check the server hosting PBIRS has sufficient RAM and CPU. Increase the MaxMemoryLimit setting in RSHostingService.config.
3. If multiple reports are refreshing simultaneously, try to refresh one by one report to reduce load.
4. Use the latest PBIRS version. Sometimes bugs in older versions cause intermittent issues.
5. Large models may fail to load under constrained resources. remove unused columns and aggregate the data.6. Re-upload the affected reports to PBIRS. Validate that the model loads correctly in PBIRS after upload.
I hope this information helps. Please do let us know if you have any further queries.
Regards,
Dinesh
Hi WithwindOK,
Can you share screenshots of the error?
Is this error happening in desktop, or only once you upload it to report server?
What are your data sources?

This error only occurs when uploading to PBIRS; refreshing in Desktop works fine. The data source is Oracle Database 19c, and a manual refresh can complete successfully.
Hi WithwindOK,
Does the server where the report server is installed have the oracle client installed?
Are you able to use TNSPING on the server to successfully connect to the database?

The Oracle client is installed correctly. Please note that the refresh fails randomly—not every time—and the reports that fail are also random.
Hi WithwindOK ,
Thank you for the update. The error message "Couldn't find database: <GUID>_<number> in AS server",
refers that during the data refresh process on Power BI Report Server, the server is unable to locate the Analysis Services database associated with the report model.Please check below things to fix the issue.
1. Please check the RSPortal.log and RSHostingService.log files for more detailed error traces around the time of failure.
2. Use Performance Monitor or Task Manager to check memory and CPU usage during refresh times.3. Avoid concurrent refreshes by scheduling reports at different times.
4. Check this issue in the September 2025 release notes or forums. If it's a confirmed bug, consider rolling back to a stable version.
I hope this information helps. Please do let us know if you have any further queries.

Your questions have left me quite confused. I've already uploaded the software version and error screenshots in my previous posts—I'm not sure what else I can do.
