Even though your data sources appear connected, Power BI frequently disables scheduled refreshes due to an expired OAuth token, a recent password change, or a minor shift in the underlying connection string. To resolve this, go to the dataset's Settings page in the Power BI service, expand Data source credentials, click Edit credentials to re-authenticate every source even if they look correct and then toggle scheduled refresh back on. You can verify this fix was successful by manually clicking Refresh Now and confirming the refresh completes without error.
