I am facing a problem with no response for now in Microsoft Power BI docs and different forums. I have a Power BI dataset scheduled refresh which it's not working and the showing message error is "Unable to connect to the data source undefined"
The dataset is connected to an SQL database hosted in a server in which is correctly installed an On-premises Gateway. The connections are to the data sources are set correctly.
When the schedule refresh runs it fails every time, when we try to refresh manually it works!
Does someone has faced this issue and how it can be handle?
Thanks for your response!
