Report Failure in Service
Hi learner03 , Thank you for reaching out to the Microsoft Fabric Community Forum.
The fact that your report refreshes successfully in Desktop but fails in the Service indicates the issue is specific to the Power BI Service environment, not the report itself. This error usually means the service is trying to access a workspace, table,or data row that it cannot find or doesn’t have permission to access.
Most likely causes are the service principal, gateway account or dataset credentials used in the Service no longer have proper access to the workspace or data source. Even if IT hasn’t intentionally changed anything, tokens can expire, credentials can become invalid or subtle permission changes may block access.
You should re-enter or test the dataset credentials in the Service, ensure the gateway account (if used) has proper permissions and confirm that the workspace and its tables are still accessible by the Service account. Desktop works because it runs under your user context, which still has access, whereas the Service uses its own account context. Once the credentials and permissions are validated, the refresh in the Service should start working again.
Likey Causes:
-
Permissions changed — your service principal / gateway account lost access to that workspace or its contents.
-
If this is querying the Power BI REST API, the API response might have changed.
-
If this is querying an external database (SQL, SharePoint), then the join key changed or the source stopped returning rows.
Shravan133 The report is refreshing in the desktop though but not just in service and asked the IT team, they said they changed nothing from their end
