DataSource Error by refreshing data on the datahub

[Anonymous]

Hi, 

I'm trying to set up automatic refresh for my datasets. When I click the reload button in Power BI Desktop, everything works fine but refreshing the dataset on app.powerbi.com causes the following error: 

(it's a onedrive folder containing CSV files) 

I've already removed all my data source permissions and reentered them again. 

Any tips? Thanks!

@Anonymous , In power bi service, using the three dots in front of the data source, go to settings and set up the data source credentials again
