Google Play Services authorization error

Hello all!

I'm making a small game in unity.. Everything works, the game works, the sound is not very but works .. everything seems to be fine .. BUT BUT BUUUTHEART.. BUT Google Play Services doesn't log in..
When I start the game up, it will say "Connecting to... Google Play Games" but then it will display a loading circle for about a second and then it just returns to the game. No "Welcome User!" at the top.

I'm lost 4 days and doesn't work... My brain broke down...

This is my code:

private void Start()
{

PlayGamesPlatform.Activate(); // START ACTIVATE
}
// IF BUTTON -
Social.localUser.Authenticate((bool success) =>
{
if (success)
{
print("Success!");
// logIn = true;
}
else print("NOT Success!");
});
break;
and two buttons achievements and leaderboards..

I'm compiled this project.. Opened close alpha.. Added few e-mail to tester list! NOTHING!!!
Ok.. In Google API changed SH1 .. First on the "Certificate for signing applications SH1" later on "Downloading the certificate SH1" and so in a circle.. and NOTHING!!! Change SH1 - rebuild apk - upload new version .. NOTHING.. Changes SH1 back - rebuild apk - upload new bersion NOTHING..
Monitor (SDK tools) shows this ..

Sorry for my ENglish.. I'm Russian.. BUT MY BRAIN IS REALLY BROKE DOWN! 4 days minus out of my life, and GPS Doesn't work... What he need?
