New Google sign in Android

I'm trying to get user token id using new Google play services 8.3 and as documented I pass the server id:

GoogleSignInOptions gso = new GoogleSignInOptions.Builder(GoogleSignInOptions.DEFAULT_SIGN_IN)
                    .requestIdToken(getString(R.string.server_client_id))
                    .requestEmail()
                    .build();

but I'm still getting un successful result as below:

{statusCode=unknown status code: 12501, resolution=null}

and documented here GoogleSignInStatusCodes

The sign in was cancelled by the user. i.e. user cancelled some of the sign in resolutions, e.g. account picking or OAuth consent.

Constant Value: 12501

which is not my case ,as I already picked an account. Any idea what could be the reason?
