Question

我有一个绑定了MongoDB实例的Bluemix应用程序。该应用已运行了大约一年。大约一个星期前，我的应用程序崩溃了，我无法重新部署它。我在日志中看到以下内容：

 Instance (index 0) failed to start accepting connections

我的代码位于google documentation的项目中。连接到MongoLab实例的方式有变化吗？为什么我会收到身份验证错误？

我通过MongoLab支持发了电子邮件。他们回答说：

我们的免费Sandbox数据库最近通过了预定版本   升级事件描述于：

http://docs.mongolab.com/20150930-maintenance-event/

在过去的几天里，我们发送了几份有关此计划维护的通知   个月。

此Sandbox数据库现在运行MongoDB 3.0.x，其中包括   更改MongoDB的身份验证机制。这个新机制是   某些较新的驱动程序版本支持，如下所述   http://docs.mongodb.org/manual/release-notes/3.0-scram/#upgrade-drivers

为了让您的应用程序连接到此数据库，您将会   需要使用上面链接中列出的其中一个驱动程序。

他们为我的应用提出了以下建议，并修复了问题：

您必须将“mongo-python-driver-master”文件夹更新为更新版本的python驱动程序。你可以下载驱动程序在这里：https://github.com/mongodb/mongo-python-driver/releases。 ID 建议使用版本2.9或3.0.3。

连接MongoLab数据库的方式是否有变化？
