Thanks for your quick answer. 
At this installation I do not changed something. They are original.
All I did bevor failed.
I want to use it at the same server.
PS: the fingerprint was never displayed during installation
# ======================== 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:
# https://www.opensearch.org
#
# ---------------------------------- 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.attr.rack: r1
#
# ----------------------------------- Paths ------------------------------------
#
# Path to directory where to store the data (separate multiple locations by comma):
#
path.data: /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
# 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: 192.168.0.1
#
# Set a custom port for HTTP:
#
#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:
#
#cluster.initial_cluster_manager_nodes: ["node-1", "node-2"]
#
# For more information, consult the discovery and cluster formation module documentation.
#
# ---------------------------------- 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

# 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.hosts: ["http://localhost:9200"]
# 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.
# opensearch.username: "opensearch_dashboards_system"
# opensearch.password: "pass"
# Enables SSL and paths to the PEM-format SSL certificate and SSL key files, respectively.
# These settings enable SSL for outgoing requests from the OpenSearch Dashboards server to the browser.
# server.ssl.enabled: false
# server.ssl.certificate: /path/to/your/server.crt
# server.ssl.key: /path/to/your/server.key
# Optional settings that provide the paths to the PEM-format SSL certificate and key files.
# These files are used to verify the identity of OpenSearch Dashboards to OpenSearch and are required when
# xpack.security.http.ssl.client_authentication in OpenSearch is set to required.
# opensearch.ssl.certificate: /path/to/your/client.crt
# opensearch.ssl.key: /path/to/your/client.key
# Optional setting that enables you to specify a path to the PEM file for the certificate
# authority for your OpenSearch instance.
# opensearch.ssl.certificateAuthorities: [ "/path/to/your/CA.pem" ]
# To disregard the validity of SSL certificates, change this setting's value to 'none'.
# opensearch.ssl.verificationMode: full
# Time in milliseconds to wait for OpenSearch to respond to pings. Defaults to the value of
# the opensearch.requestTimeout setting.
# opensearch.pingTimeout: 1500
# Time in milliseconds to wait for responses from the back end or OpenSearch. This value
# must be a positive integer.
# opensearch.requestTimeout: 30000

# opensearch.logQueries: false
# Specifies the path where OpenSearch Dashboards creates the process ID file.
# pid.file: /var/run/opensearchDashboards.pid
# Enables you to specify a file where OpenSearch Dashboards stores log output.
# logging.dest: stdout
# Set the value of this setting to true to suppress all logging output.
# logging.silent: false
# Set the value of this setting to true to suppress all logging output other than error messages.
# logging.quiet: false
# Set the value of this setting to true to log all events, including system usage information
# and all requests.

# Set the interval in milliseconds to sample system and process performance
# metrics. Minimum is 100ms. Defaults to 5000.
# ops.interval: 5000
# Specifies locale to be used for all localizable strings, dates and number formats.
