Hi XuYang1795 

 

Thank you for the direction.  I ran a test using the msal4j.jar using your example code and the output told me specifically that my client secret keys are expired:


Error occurred: com.microsoft.aad.msal4j.MsalServiceException: AADSTS7000222: The provided client secret keys for app 'fba4660b-7c4e-4c7f-887f-7960dff2cfcf' are expired. Visit the Azure portal to create new keys for your app: https://aka.ms/NewClientSecret, or consider using certificate credentials for added security: https://aka.ms/certCreds.
