Подключения Google Play Service к проекту Unity3D. (Ошибка "authentication failed - developer error")

Люди добрые, столкнулся с проблемой, которая застопорила меня уже как на неделю. Дело в общем вот какое : Решил я значиться подключить к игре Google Service. Вроде всё настроил, и все коды ввёл правильно. OAuth2 настроил. Запускаю : Игра запускается, после на секунду зависает и темнеет экран (Прям видно что идёт попытка подключения), отвисает и ничего. Вообще ничего. Прогнал через Logcat, получил вот такой лог:
