ID3242: The security token could not be authenticated or authorized error in Report Designer (Dynamics 365, CRM 2016 Online)

While working on Report we suddenly started getting the below error

The strange thing was that the other reports that were using the same data source in the same Report Project were working properly.

Find few posts

but none applied here.

Tried creating a new data source, entered credentials repeatedly but nothing worked, eventually restarted the SQL Server Data Tools (IDE) and it fixed the issue.

Hope it helps..
