Cannot refresh data

[anonymous888]

I can't set up the refresh of my Power BI dashboard it is giving Data source error: Scheduled refresh is disabled because at least one data source is missing credentials. To start the refresh again, go to this dataset's settings page and enter credentials for all data sources. Then reactivate the scheduled refresh. But data source credentials tab is grayed out for me and I tried editing data source settings and setting security to none, but the error persists.

Hi @anonymous888 

Clearly you need a Power BI Gateway installed On-Prem
