We have created a report in Power BI desktop that loads data from Azure SQL (Not direct query). We published the report under the Power BI service and the refresh data set worked for a while.
Recently it stopped working for some reason and this is what shows up on the Dataset settings page:

There is no option to change the database credentials or anything similar. It used to be there...
We have many reports based on that data set, so renaming the dataset and republishing it is not an option.
Thanks!
