Excel refresh fail

[Anonymous]

I'm setting up, but customer request, an Excel file which contains a query from Azure Data Warehouse. I can populate and update the data in Excel. I saved it to OneDrive for business, and from there, I uploaded the workbook to Power BI. I can open it in Power BI and see the data.

However; when I try to refresh the data, it fails, and this is the only explanation I get for the failure. I don't really know how to troubleshoot the cause of the failure from here:
