Data source refresh is disabled because at least one data source is missing credential

[Eliasnaevdal]

My datasource is my teams sharepoint folder. 

Refresh is working in the Power BI Desktop, but does not work in the published one.  

It is not possible to access the "Data Source cerdentials" in settings.

Yes, when you publish a new report that has a SharePoint datasource, you need to open up the credentials and enter them before it will let you refresh. The type should be OAuth 2 (it'll default to anonymous).
