Hi @asottocornola ,
You can try this step to examine issue:
Verify ODBC Connection: Ensure that the ODBC connection to your MariaDB database is correctly configured and that the Power BI report server can access it. This includes verifying the DSN (Data Source Name) settings and ensuring that the necessary drivers are installed on the server hosting the Power BI Report Server.
Check Data Source Support: While Power BI supports a wide range of data sources for scheduled refreshes, there are specific configurations, especially with ODBC connections, that may require additional steps. Review the documentation on Data refresh in Power BI Report Server to ensure your setup meets the necessary criteria for scheduled refreshes.
Best Regards,
Xianda Tang
