Hi All,

I'm new to Elasticsearch. I've installed elasticsearch 6.7.0 on Centos6.9. It is a single cluster node. I can successfully curl it on same machine. curl -XGET "[http://xxx.xxx.xx.xx:9200](http://xxx.xxx.xx.xx:9200)" I get the following result

```
    {
  "name" : "........",
  "cluster_name" : ".................",
  "cluster_uuid" : "..........",
  "version" : {
    "number" : "6.7.0",
    "build_flavor" : "default",
    "build_type" : "rpm",
    "build_hash" : "......",
    "build_date" : "......",
    "build_snapshot" : false,
    "lucene_version" : "7.7.0",
    "minimum_wire_compatibility_version" : "5.6.0",
    "minimum_index_compatibility_version" : "5.0.0"
  },
  "tagline" : "You Know, for Search"
}

```

But I couldnt connect to elasticsearch from other system, It says curl(7): Failed to connect to xxx.xxx.xx.xx port 9200 : Timed out. I check the firewall settings, it is open and in my elasticsearch.yml file,

```
# ---------------------------------- Network -----------------------------------
#
# Set the bind address to a specific IP (IPv4 or IPv6):
#
network.host: 0.0.0.0
http.host: 0.0.0.0
transport.host: localhost
network.bind_host: 0.0.0.0
http.cors.allow-origin: "*"
http.cors.enabled: true
#
# Set a custom port for HTTP:
#
http.port: 9200
transport.tcp.port: 9300

```

Any help is greatly appreciated. Thanks in advance

Can you share elasticsearch starting logs?  
Is there any reason you are masking the IP address here? Do you mean that it's a public IP and that you are exposing your elasticsearch cluster on internet?

Yes, I've installed my elasticsearch in my testserver and I tried to connect to it locally from my system. I couldnt connect through curl or browser.

Don't expose your cluster on internet without any protection.

You can have a look at [cloud.elastic.co](http://cloud.elastic.co) where you can have a secured cluster up and running in few minutes.

But if you really want to do it:

Change `network.host` setting to bound it to the public IP of your server.

Thanks for your support. I'll check cloud.elastic.
