SQL Server Connected system OAuth2.0 Test failure

Certified Associate Developer

Hi, 

While trying to connect to SQL Server connected system using OAuth 2.0, the test connection is failing. 
i am trying to connect via service principal. The token generation is successful (tested separately) but in the connected system for SQL Server, it is not working at all. 
Please advise,
