Unable to refresh Semantic Model for development workspace in Microsoft Fabric
If re-entering credentials didn’t work, the issue is likely with the SQL Server gateway connection. Could you please try below steps:
-
Check Gateway – Go to Fabric Workspace › Manage Gateways and ensure a standard gateway is online and mapped to your SQL Server.
-
Re-map Connection – In Semantic Model › Settings › Gateway connection, pick the correct gateway + data source and refresh.
-
Network Access – Confirm SQL Server firewall allows Fabric/Gateway IPs (port 1433).
-
Authentication – Make sure the auth method (Windows/Basic/OAuth) matches what’s used in Desktop.
-
Re-publish if needed – Open the .pbix in Power BI Desktop >> refresh >> publish again to Fabric.
-
This issue usually happens when the semantic model migrated from Power BI Service to Microsoft Fabric still points to old connections or has missing credentials.
Could you please try below steps:
-
Rebind the dataset
-
Go to Fabric Workspace >> Semantic Models.
-
Open the dataset and reconnect it to the correct Lakehouse or Warehouse instead of the old Power BI source.
-
-
Re-enter credentials
-
Go to Workspace >> Data Source Credentials and sign in again for each source.
-
Credentials don’t automatically migrate from Power BI Service.
-
-
Check refresh mode
-
Ensure the dataset is using the right mode (Direct Lake or Import) and that the workspace and Lakehouse are in the same region.
-
-
Retry after a few minutes
-
The error “Internal service error, transient issue” can be temporary. Wait 15–30 min and refresh again.
-
-
If still failing:
-
Download the .pbix >> open in Power BI Desktop >> republish to your Fabric workspace to re-establish the connection.
-
I have tried entering the credentials again, but no luck, data source is connected to sql server.
