High severitygateway
Power BI Refresh Error:
A gateway is required but none is configured
What does this error mean?
The dataset uses a data source that requires an on-premises data gateway, but no gateway is associated with this dataset in Power BI Service.
Common causes
- 1The dataset was published for the first time and gateway setup was not completed in Power BI Service
- 2The gateway that was previously associated was uninstalled or removed
- 3The dataset was moved to a different workspace where the gateway cluster is not shared
- 4The gateway was removed from the organization's gateway cluster by an admin
- 5The data source connection string changed and the new connection is not mapped to any gateway source
How to fix it
- 1Go to Power BI Service → Settings → Datasets → select the dataset → Gateway connections.
- 2If a gateway is available in the list, map the dataset's data source to the correct gateway source.
- 3If no gateway appears, install the on-premises data gateway on a machine that can reach the data source.
- 4Ensure the gateway admin has shared the gateway with your workspace or your account.
- 5After mapping, trigger a manual refresh to verify the gateway connection is working before relying on scheduled refresh.
