High severitydata source
Power BI Refresh Error:
DataSource.NotFound
What does this error mean?
Power Query cannot find or access the data source. The source is unreachable, moved, or the user lacks permissions to access it.
Common causes
- 1The file path or URL of the data source has changed since the query was created
- 2The user running the refresh does not have permission to access the data source
- 3The data source server or service is offline or temporarily unavailable
- 4Network path to a local file or UNC share is not accessible from the gateway machine
- 5The database name or table name referenced in the query no longer exists
How to fix it
- 1Open Power BI Desktop and click Refresh — the Query Editor will identify the exact failing step
- 2Check whether the source file or database connection string still points to a valid location
- 3In Power BI Service, go to dataset Settings → Data source credentials and verify the credentials are current
- 4If accessing a file share, confirm the gateway service account has read access to the UNC path
- 5If the source was moved or renamed, update the connection in Power BI Desktop and republish
