Question

我正在使用Nest.ElasticClient连接到Elasticsearch集群。群集位于Azure VM中，只有一个节点。

群集可以通过url：http://xxxx.cloudapp.net:9200在vm外部访问，如果不使用SniffingConnectionPool，也可以通过ElasticClient访问。但是如果使用SniffingConnectionPool，ElasticClient无法访问。

这是网络配置

network.host: [_local_, _site_]

下面是我用来获取客户端和检查索引的源代码。

var pool = new SniffingConnectionPool(urls.Select(url => new Uri(url)));
ConnectionSettings config = new ConnectionSettings(pool) ;
client = new Nest.ElasticClient(config);
IExistsResponse indexExistsResponse = client.IndexExists(indexName);

当我尝试使用客户端检查索引是否存在，hostnanme和ip地址被修改时的调试信息消息：
