No Output Received from Opensearch Server

The opensearch service shows as active and running when I run the command systemctl status opensearch

However, I get no output when I try to send a get request to the cluster’s root endpoint. using curl -X GET “#http#://localhost:9200” - note: I had to add the ‘#’ before and after http to prevent this comment field from seeing it as a link, as only one link is allowed for new users

The opensearch yaml file looks like below:

======================== OpenSearch Configuration =========================

NOTE: OpenSearch comes with reasonable defaults for most settings.

Before you set out to tweak and tune the configuration, make sure you

understand what are you trying to accomplish and the consequences.

The primary way of configuring a node is via this file. This template lists

the most important settings you may want to configure for a production cluster.

Please consult the documentation for further information on configuration options:

---------------------------------- Cluster -----------------------------------

Use a descriptive name for your cluster: graylog

------------------------------------ Node ------------------------------------

Use a descriptive name for the node: ${HOSTNAME}

Add custom attributes to the node:

#node.attr.rack: r1

----------------------------------- Paths ------------------------------------

Path to directory where to store the data (separate multiple locations by comma): /var/lib/opensearch

Path to log files:

path.logs: /var/log/opensearch

----------------------------------- Memory -----------------------------------

Lock the memory on startup:

#bootstrap.memory_lock: true

Make sure that the heap size is set to about half the memory available

on the system and that the owner of the process is allowed to use this


OpenSearch performs poorly when the system is swapping the memory.

---------------------------------- Network -----------------------------------

Set the bind address to a specific IP (IPv4 or IPv6):

Set a custom port for HTTP:

#http#.port: 9200 note: I had to add the ‘#’ before and after http to prevent this comment field from seeing it as a link, as only one link is allowed for new users

For more information, consult the network module documentation.

--------------------------------- Discovery ----------------------------------

Pass an initial list of hosts to perform discovery when this node is started:

The default list of hosts is [“”, “[::1]”]

#discovery.seed_hosts: [“”]

Bootstrap the cluster using an initial set of cluster-manager-eligible nodes:

#cluster.initial_cluster_manager_nodes: [“”]

For more information, consult the discovery and cluster formation module documentation.

discovery.type: single-node

---------------------------------- Gateway -----------------------------------

Block initial recovery after a full cluster restart until N nodes are started:

#gateway.recover_after_nodes: 3

For more information, consult the gateway module documentation.

---------------------------------- Various -----------------------------------

Require explicit names when deleting indices:

#action.destructive_requires_name: true

---------------------------------- Remote Store -----------------------------------

Controls whether cluster imposes index creation only with remote store enabled

cluster.remote_store.enabled: true

Repository to use for segment upload while enforcing remote store for an index

node.attr.remote_store.segment.repository: my-repo-1

Repository to use for translog upload while enforcing remote store for an index

node.attr.remote_store.translog.repository: my-repo-1

---------------------------------- Experimental Features -----------------------------------

Gates the visibility of the experimental segment replication features until they are production ready.

OpenSearch.experimental.feature.segment_replication_experimental.enabled: false

Gates the functionality of a new parameter to the snapshot restore API

that allows for creation of a new index type that searches a snapshot

directly in a remote repository without restoring all index data to disk

ahead of time.

OpenSearch.experimental.feature.searchable_snapshot.enabled: false

Gates the functionality of enabling extensions to work with OpenSearch.

This feature enables applications to extend features of OpenSearch outside of

the core.

OpenSearch.experimental.feature.extensions.enabled: false

Gates the optimization of datetime formatters caching along with change in default datetime formatter

Once there is no observed impact on performance, this feature flag can be removed.

OpenSearch.experimental.optimization.datetime_formatter_caching.enabled: false

Gates the functionality of enabling Opensearch to use pluggable caches with respective store names via setting.

OpenSearch.experimental.feature.pluggable.caching.enabled: false

action.auto_create_index: false
indices.query.bool.max_clause_count: 32768 true

Hey @Oluwatelid,
what happens when you add -vvv in your curl Command?
Your Command should at least give a brief overview over your OpenSearch Installation but maybe there is something off and with -vvv you see what’s wrong.
