Failed to preview report.
Hi Anonymous ,
Ensure Report Builder uses your Windows credentials for the SharePoint data source and that you can access the URL directly in a browser. Running Report Builder as Administrator might also help.

I began encountering this error when utilizing a shared datasorce. When I do not use a shared datasource, I can preview the report without any issues. However, the moment I incorporate the shared dataset, the error occurs.
I confirmed this by using a standard SQL connection, which functions properly and allows me to preview the report. So I belive that the database drivers are not the the problem.
Furthermore, I tried importing the shared datasource, assigned a standard title, and ran the report, but I encountered the same error. It is worth noting that since the dataset has not been added, size should not be a concern.
Hi Anonymous ,
From the information provided, it looks like the issue might be related to the configuration or permissions of the shared datasource. Here are some reasons that might help you.
1.Shared datasource might not have the necessary permissions to access the data when the report is run.Check the permissions.
2.Double-check the configuration settings for the shared datasource.
3.Clear any cached data in Report Builder which might cause issues when previewing newly created reports.
