Failed to update data source credentials: The credentials provided for the OData source are invalid

Hello Community!

I have a data set created. i can manualy refresh it with no problem. Wheni'm trying to schedule a refresh, iu get the notification that the credential provided are invalid. 

Assuming my credentials are correct, how do i solve it?

Also, Is there a way to see what were the credentials i used when craeting the dataset?

Thanks,

Amir
