Answer 1

我在 Android 4.4 中遇到了完全相同的问题。

对我来说，是 Google Play 服务过时了。 我在日志中发现：

 Google Play services out of date.  Requires 12451000 but found 4325036

您可以通过进入 Google Play 商店并安装 Google Play 服务的更新来解决此问题。

Answer 2

我Failure in SSL library, usually a protocol error 。 当我注意到我的 wifi 已关闭并再次打开它并且我的互联网连接良好时，错误消失了。
