powerbi – Unable to get Sharepoint Online data Web data source for Power BI

What I wanted to do is to get the data for Power BI from web datasource. The excel data was uploaded in sharepoint online as document and then I copied link for url data source on the power BI side. It was working perfectly few days ago. But now whenever I want to retrieve data from web it always says “


web browsercontents currently supports only anonymous credentials

enter image description here

Even if I clear the global permission through File>Options and Settings>Data source Settings>Global Permission>Clear All Permission, the results is still unable to get the data from web source. What could go wrong?
Any suggesiont?I have been 3 days stuck in this problem and unable to solve it until now.

Appreciate for your help.
