将Java-Application连接到MongoDB-com.mongodb.MongoSocketReadException:过早到达流的末尾

Question

在我的应用程序中，我使用MongoDB，它在本地与Wildfly 11.0.0一起工作得很好。Alpha1-部署在本地应用程序服务器和本地MongoDB数据库后，应用程序可以在上下文路径和端口上访问-一切都很好。

我的下一步是将这个应用程序部署到服务器maschine上的JBoss服务器上。我将MongoDB URI更改为MongoDB服务器：

mongodb://user:password@server:27017/databaseName?authMechanism=SCRAM-SHA-1&ssl=true

如果我部署这个应用程序，我会在底部得到以下日志条目。实际上我不知道为什么，也不知道这意味着什么。有人告诉我在这种情况下我能做些什么来解决这个问题吗？

这可能与与mongob连接上发生的超时有关。尝试在构建连接时通过使用API来增加超时

  MongoClientOptions.Builder builder = new MongoClientOptions.Builder();
builder.maxConnectionIdleTime(<long_time>);

或者试着去掉上面写着不超时的
