Hi, I can't figure out why Elasticsearch still can't be reached from the public ip of the ec2 instance. This is my config file cloud.aws.access\_key: "AKIAXXXXXXXXXPWEW2A" cloud.aws.secret\_key: "EvU0I5XXXXXXXXXXXXXx+b+FlRXXXSSDFfM2Z" plugin.mandatory: "cloud-aws" cluster.name: "escluster" node.name: "Iron Fist" discovery.type: "ec2" discovery.ec2.groups: "launch-wizard-4" discovery.ec2.host\_type: "public\_ip" discovery.ec2.ping\_timeout: "30s" discovery.ec2.availability\_zones: "us-east-1a" cloud.aws.region: "us-east" discovery.zen.ping.multicast.enabled: false network.publish\_host: "54.31.403.195" Do you have a hint for me? Curl-ing the private ip works. Your help is much appreciated. Thank you, best regards -- You received this message because you are subscribed to the Google Groups "elasticsearch" group.

Hi Martin, Did you check your firewall settings? Did you open 9200 ports so they can be accessible from your local machine? BTW, those settings are not used. You can comment/remove them: discovery.zen.ping.multicast.enabled: false network.publish\_host: "54.31.403.195" -- David Pilato | Technical Advocate | [elasticsearch.com](http://elasticsearch.com) [david.pilato@elasticsearch.com](mailto:david.pilato@elasticsearch.com) @dadoonet | @elasticsearchfr | @scrutmydocs Le 19 octobre 2014 à 07:40:46, [martin.enzinger@gmail.com](mailto:martin.enzinger@gmail.com) ([martin.enzinger@gmail.com](mailto:martin.enzinger@gmail.com)) a écrit: Hi, I can't figure out why Elasticsearch still can't be reached from the public ip of the ec2 instance.
