C# – Google Play Games Service : ERROR_NOT_AUTHORIZED, when rollout for Beta

Google Play Games Service : SIGN_IN status: ERROR_NOT_AUTHORIZED, when rollout for Beta.
And also this :-

W Auth    : [GetToken] GetToken failed with status code: UNREGISTERED_ON_API_CONSOLE
E TokenRequestor: You have wrong OAuth2 related configurations, please check. Detailed error: UNREGISTERED_ON_API_CONSOLE

If i Build and Run Directly from Unity , everything works fine.
But When i Rollout a Beta, it shows Sign In Google green box with a loading circle (then accounts -> select beta tester Email), and then nothing.

Using :-

• GooglePlayGamesPlugin-0.9.38a
• unity 5.6.03
• sdk components updated rev 40 , rev 51

Things i did :-

1. Created a new application google play console
2. added apk, made beta and then production rollout.
3. later i added play game services in new update , made beta rollout.
4. note – all apk , rollout use same keystore and package name.
5. Google Play Console -> Release Management -> App signing : Upload
   certificate SHA1 is same as Google API -> Project -> Client ID for
   Android SHA1

Play game settings :-

• Beta tester Emails : Open
• game save data : off
• Testing emails : emails added
• testing for Alpha and Beta : both tick (green)
