Hi , @anadar
According to my testing experience and research in the official documentation, generally after the failure of four scheduled refreshes, Power BI will automatically disable scheduled refresh for your dataset, and your description is that your scheduled refresh will be disabled every four days, which means that your dataset is refreshed once a day, and each time it fails, and the specific error cause of refresh failure will be expanded in your refresh history. I also tried to check the cause of your error in the internal data provided according to your information, but the error details seem to be encrypted, so you can expand here and view your specific error message and fix it if it is convenient:
