# ======================== 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 opti                                                                                                             ons:

#
# ---------------------------------- Cluster -----------------------------------
#
# Use a descriptive name for your cluster:
#
#cluster.name: my-application
#
# ------------------------------------ Node ------------------------------------
#
# Use a descriptive name for the node:
#
#node.name: node-1
#
# Add custom attributes to the node:
#node.max_local_storage_nodes
#node.attr.rack: r1
#
# ----------------------------------- Paths ------------------------------------

# Path to directory where to store the data (separate multiple locations by comm                                                                                                             a):

# Path to log files:

#
# ----------------------------------- 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
# limit.
#
# OpenSearch performs poorly when the system is swapping the memory.
#
# ---------------------------------- Network -----------------------------------
#
# Set the bind address to a specific IP (IPv4 or IPv6):
#
#network.host: localhost
network.host: 0.0.0.0
# Set a custom port for HTTP:
#network.host: 172.31.4.236
http.port: 9200
#
# 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 ["127.0.0.1", "[::1]"]
#
#discovery.seed_hosts: ["host1", "host2"]
#
# Bootstrap the cluster using an initial set of cluster-manager-eligible nodes:
discovery.type: single-node
#cluster.initial_cluster_manager_nodes: ["node-1", "node-2"]
#
# For more information, consult the discovery and cluster formation module docum                                                                                                             entation.

# Description:
# Default configuration for OpenSearch Dashboards

# OpenSearch Dashboards is served by a back end server. This setting specifies the port to use.
server.port: 5601

# Specifies the address to which the OpenSearch Dashboards server will bind. IP addresses and host names are both valid values.
# The default is 'localhost', which usually means remote machines will not be able to connect.
# To allow connections from remote users, set this parameter to a non-loopback address.
server.host: "localhost"

# Enables you to specify a path to mount OpenSearch Dashboards at if you are running behind a proxy.
# Use the `server.rewriteBasePath` setting to tell OpenSearch Dashboards if it should remove the basePath
# from requests it receives, and to prevent a deprecation warning at startup.
# This setting cannot end in a slash.
# server.basePath: ""

# Specifies whether OpenSearch Dashboards should rewrite requests that are prefixed with
# `server.basePath` or require that they are rewritten by your reverse proxy.
# server.rewriteBasePath: false

# The maximum payload size in bytes for incoming server requests.
# server.maxPayloadBytes: 1048576

# The OpenSearch Dashboards server's name.  This is used for display purposes.
# server.name: "your-hostname"

# The URLs of the OpenSearch instances to use for all your queries.

# OpenSearch Dashboards uses an index in OpenSearch to store saved searches, visualizations and
# dashboards. OpenSearch Dashboards creates a new index if the index doesn't already exist.
# opensearchDashboards.index: ".opensearch_dashboards"

# The default application to load.
# opensearchDashboards.defaultAppId: "home"

# Setting for an optimized healthcheck that only uses the local OpenSearch node to do Dashboards healthcheck.
# This settings should be used for large clusters or for clusters with ingest heavy nodes.
# It allows Dashboards to only healthcheck using the local OpenSearch node rather than fan out requests across all nodes.
#
# It requires the user to create an OpenSearch node attribute with the same name as the value used in the setting
# This node attribute should assign all nodes of the same cluster an integer value that increments with each new cluster that is spun up
# e.g. in opensearch.yml file you would set the value to a setting using node.attr.cluster_id:
# Should only be enabled if there is a corresponding node attribute created in your OpenSearch config that matches the value here
# opensearch.optimizedHealthcheckId: "cluster_id"

# If your OpenSearch is protected with basic authentication, these settings provide
# the username and password that the OpenSearch Dashboards server uses to perform maintenance on the OpenSearch Dashboards
# index at startup. Your OpenSearch Dashboards users still need to authenticate with OpenSearch, which
# is proxied through the OpenSearch Dashboards server.

Hi @rathiga ,

Is this a single-node cluster? are there any other clusters on the same network?

I would recommend giving your cluster a unique name, more on a cluster.name here: Creating a cluster - OpenSearch Documentation

Moreover please add plugins.security.ssl.transport.enforce_hostname_verification: false to your opensearch.yml:

best,
mj

one more thing, could you test with server.host: '0.0.0.0'

best,
mj
