使用.Net mongodb驱动程序托管ubuntu 16.04 LTS时，Atlas MongoDB获取超时发生在30000ms之后 [英] Atlas MongoDB getting timeout occured after 30000ms when hosted ubuntu 16.04 LTS, using .Net mongodb driver

问题描述

从具有mongo驱动程序2.7.3的本地系统.NET标准2.0连接到Atlas mongodb并列出更改流的工作情况.

From local system .NET standard 2.0 with mongo driver 2.7.3 connecting to Atlas mongodb and listing change stream working.

当我在ubuntu 16.04 LTS上部署相同的系统时，它抛出以下错误.

When i deploy the same system on to ubuntu 16.04 LTS it is throwing below error.

连接字符串:

mongodb://xxxxxx:xxxxx@mycluster-shard-00-00- 
xxxx.mongodb.net:27017,mycluster-shard-00-01- 
xxxx.mongodb.net:27017,mycluster-shard-00-02-xxxx.mongodb.net:27017/test?ssl=true& 
replicaSet=Cluster-shard-0&retryWrites=true

错误:

推荐答案

MongoDb Atlas免费软件不支持变更流，这就是我们面临此问题的原因.

MongoDb Atlas freeware not supporting change streams, that's why we were faced this issue.

当MongoDb安装在AWS EC2实例中时，它可以正常工作，我们能够连接和侦听变更流.

It's working fine when MongoDb installed in AWS EC2 instance, we are able to connect and listen change streams.
