org.elasticsearch.client.transport.NoNodeAvailableException

集群节点数：4
集群健康值：green (10 of 10)
不知道哪里配置不对了，在数据索引进行插入中报错，在查看了很多文档资料后没有解决此问题,具体报错如下：
Exception in thread "main" org.elasticsearch.client.transport.NoNodeAvailableException: None of the configured nodes are available:

只有主节点内容变化，子节点内容不变只显示启动后的日志？不知道是不是这样的。。。
主节点日志内容如下（IP地址已修改为*）：
