By default Elasticsearch binds only to localhost which means it cannot be accessed remotely. This configuration is sufficient for a local development cluster made of one or more nodes all running on the same host.

How do I set up a remote Elasticsearch cluster?
Select Remote Clusters from the side navigation. Specify the Elasticsearch endpoint URL, or the IP address or host name of the remote cluster followed by the transport port (defaults to 9300 ). For example, cluster.es.eastus2.staging.azure.foundit.no:9400 or 192.168.1.1:9300 .
Why is Elasticsearch not compressing my response?
Similarly, Elasticsearch will not compress a response if the inbound request was uncompressed—even when compression is enabled. The compression scheme used to compress a response will be the same scheme the remote node used to compress the request. You can trace individual requests made on the HTTP and transport layers.
Does Elasticsearch disrupt the operation of your cluster?
Nonetheless, Elasticsearch requires these connections to remain open, and it can disrupt the operation of your cluster if any inter-node connections are closed by an external influence such as a firewall.
How do I configure Elasticsearch to automatically determine the host address?
You can configure Elasticsearch to automatically determine its addresses by using the following special values. Use these values when configuring network.host, network.bind_host, network.publish_host, and the corresponding settings for the HTTP and transport interfaces. Any loopback addresses on the system, for example 127.0.0.1 .
Where is the config file for ElasticSearch?
For those one who can't locate the config file on Windows please check the C:ProgramDataElasticElasticsearchconfiglocation. If you want to connect programmatically to Elasticsearch you may need to set transport.host: 0.0.0.0in elasticsearch.ymlfile.
Does elasticsearch listen to localhost?
By default http transport and internal elasticsearch transport only listens to localhost. If you want to access Elasticsearch from the host other than localhost then try adding following configurations in config/elasticsearch.yml.
Does ElasticSearch work on VirtualBox?
Tested on Elasticsearch 7.1.0 - the solutions works fine connecting to ES on VirtualBox.
Connect to remote clusters edit
Your local cluster uses the transport interface to establish communication with remote clusters. The coordinating nodes in the local cluster establish long-lived TCP connections with specific nodes in the remote cluster. Elasticsearch requires these connections to remain open, even if the connections are idle for an extended period.
Dynamically configure remote clusters edit
Use the cluster update settings API to dynamically configure remote settings on every node in the cluster. The following request adds three remote clusters: cluster_one, cluster_two, and cluster_three.
Statically configure remote clusters edit
If you specify settings in elasticsearch.yml, only the nodes with those settings can connect to the remote cluster and serve remote cluster requests.
How does Elasticsearch work?
Each Elasticsearch node has two different network interfaces. Clients send requests to Elasticsearch’s REST APIs using its HTTP interface, but nodes communicate with other nodes using the transport interface. The transport interface is also used for communication with remote clusters, and by the deprecated Java transport client.
How to bind Elasticsearch to multiple addresses?
Use the advanced network settings if you wish to bind Elasticsearch to multiple addresses, or to publish a different address from the addresses to which you are binding. Set network.bind_host to the bind addresses, and network.publish_host to the address at which this node is exposed. In complex configurations, you can configure these addresses differently for the HTTP and transport interfaces.
How many publish addresses does Elasticsearch have?
Each Elasticsearch node has an address at which clients and other nodes can contact it, known as its publish address. Each node has one publish address for its HTTP interface and one for its transport interface. These two addresses can be anything, and don’t need to be addresses of the network interfaces on the host.
What is static node?
( Static ) Sets the address of this node for both HTTP and transport traffic. The node will bind to this address and will also use it as its publish address. Accepts an IP address, a hostname, or a special value .
What are the requirements for a node to be accessible?
The only requirements are that each node must be: Accessible at its transport publish address by all other nodes in its cluster, and by any remote clusters that will discover it using Sniff mode . Accessible at its HTTP publish address by all clients that will discover it using sniffing.
Why disable HTTPS compression?
Disabling compression for HTTPS mitigates potential security risks, such as a BREACH attack. To compress HTTPS traffic, you must explicitly set http.compression to true.
Can elasticsearch be accessed remotely?
By default Elasticsearch binds only to localhost which means it cannot be accessed remotely. This configuration is sufficient for a local development cluster made of one or more nodes all running on the same host. To form a cluster across multiple hosts, or which is accessible to remote clients, you must adjust some network settings such as network.host.
