我在Azure上安装了ubuntu服务器VM，在那里我安装了couchbase社区版本，现在我需要使用dotnet访问couchbase，但是代码给了我桶，找不到或者无法到达的错误。甚至我也尝试配置一个公共dns，并在集群创建过程中将它作为ip提供，但仍然是如此。甚至我在主机文件中添加了公共dns，比如下面的127.0.0.1公共dns，SDK日志包括以下2条语句，试图在端点"name.eastus.cloudapp.azure.com“上引导失败。(e80489ed)连接尝试失败是因为连接方在一段时间后没有正确响应，或者建立连接失败是因为连接主机没有响应。

SDK医生日志：

我添加了18091和11207端口作为入站规则。我的ufw状态是不活动的，上面提到的两个端口没有监听。

感谢您提供如此详细的信息！我怀疑当前的问题是，您正在尝试使用TLS进行连接，Couchbase Community不支持TLS(至少在2022年2月不支持TLS)。端口11207和18091用于TLS连接；正如您在lsof输出中看到的那样，服务器没有监听这些端口。
