I have AWS EC2 instance to run elasticSearch. I launched it with one IP (54.xxx.xxx.109). Then I changed the IP of the instance to another IP. I have changed the ip in host files and elasticsearch.yml configs etc. But I'm getting this error. It shows the Old IP in the error. Can anybody guide me on this? I rebooted the system too. log4j, [2015-01-30T09:46:00.265] WARN: org.elasticsearch.discovery.zen: [logstash-ec2-54-xxx-xxx-56.compute-1.amazonaws.com-3633-4038] failed to connect to master [[Steve Rogers][mRLFFqUTSuWmnoAbCDv1kA][[ec2-54-xxx-xxx-56.compute-1.amazonaws.com](http://ec2-54-xxx-xxx-56.compute-1.amazonaws.com)][inet[/54.xxx.xxx.109:9300]]], retrying... org.elasticsearch.transport.ConnectTransportException: [Steve Rogers][inet[/54.xxx.xxx.109:9300]] connect\_timeout[30s] at org.elasticsearch.transport.netty.NettyTransport.connectToChannels(NettyTransport.java:718) at org.elasticsearch.transport.netty.NettyTransport.connectToNode(NettyTransport.java:647) -- You received this message because you are subscribed to the Google Groups "elasticsearch" group.
