SonarQube login error with AAD accounts

Hi Team,

I am using SonarQube version 6.7.3.38370 for C# language
Added below plugins
Azure Active Directory (AAD) Authentication Plug-in for SonarQube - 1.0
SonarC# - 7.0.1(Build 4822)
SoanrTS - 1.6 (Build 2388)

I have tried login to SonarQube URL from admin & other locally (On SonarQube server portal ) created users able to login, but getting below error while trying to login with any AAD account,
“You’re not authorized to access this page. Please contact the administrator.”

I am getting this error from last month, before to that is was working, & suddenly start getting error.

Please help.
