Unable to run ElasticSearch after setting up SSL certificate

Hey
I've followed the following guide to setup the SSL certificate for my Elasticsearch which is running on Ubuntu 22.04.1 LTS: https://www.elastic.co/guide/en/elasticsearch/reference/current/security-basic-setup.html
It's my first time setting up Elasticsearch, thus I only run it on 1 server (which means I use 1 node for now, which also runs Kibana).
Basically, I've run the following:

sudo su
cd /usr/share/elasticsearch
./bin/elasticsearch-certutil ca
Enter (to accept the default name elastic-stack-ca.p12)
Password was entered
./bin/elasticsearch-certutil cert --ca elastic-stack-ca.p12
Enter (to accept the default name elastic-certificates.p12)
The SAME password was entered
chown root:elasticsearch elastic-certificates.p12
chmod 660 elastic-certificates.p12
mv elastic-certificates.p12 /etc/elasticsearch
./bin/elasticsearch-keystore add xpack.security.transport.ssl.keystore.secure_password
SAME password was entered
./bin/elasticsearch-keystore add xpack.security.transport.ssl.truststore.secure_password
SAME password was entered

This is my /etc/elasticsearch/elasticsearch.yml:

# ======================== Elasticsearch Configuration =========================
#
# NOTE: Elasticsearch 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.elastic.co/guide/en/elasticsearch/reference/index.html
#
# ---------------------------------- Cluster -----------------------------------
#
# Use a descriptive name for your cluster:
#
cluster.name: IT-Network
#
# ------------------------------------ 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/elasticsearch
#
# Path to log files:
#
path.logs: /var/log/elasticsearch
#
# ----------------------------------- 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.
#
# Elasticsearch performs poorly when the system is swapping the memory.
#
# ---------------------------------- Network -----------------------------------
#
# By default Elasticsearch is only accessible on localhost. Set a different
# address here to expose this node on the network:
#
#network.host: 192.168.0.1
#
# By default Elasticsearch listens for HTTP traffic on the first free port it
# finds starting at 9200. Set a specific HTTP port here:
#
#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 master-eligible nodes:
#
#cluster.initial_master_nodes: ["node-1", "node-2"]
#
# For more information, consult the discovery and cluster formation module documentation.
#
# --------------------------------- Readiness ----------------------------------
#
# Enable an unauthenticated TCP readiness endpoint on localhost
#
#readiness.port: 9399
#
# ---------------------------------- Various -----------------------------------
#
# Allow wildcard deletion of indices:
#
#action.destructive_requires_name: false
 
#----------------------- BEGIN SECURITY AUTO CONFIGURATION -----------------------
#
# The following settings, TLS certificates, and keys have been automatically      
# generated to configure Elasticsearch security features on 23-08-2022 12:55:53
#
# --------------------------------------------------------------------------------
 
# Enable security features
xpack.security.enabled: true
 
xpack.security.enrollment.enabled: true
 
# Enable encryption for HTTP API client connections, such as Kibana, Logstash, and Agents
xpack.security.http.ssl:
  enabled: true
  verification_mode: certificate
  keystore.path: elastic-certificates.p12
  truststore.path: elastic-certificates.p12
 
# Enable encryption and mutual authentication between cluster nodes
xpack.security.transport.ssl:
  enabled: true
  verification_mode: certificate
  client_authentication: required
  keystore.path: elastic-certificates.p12
  truststore.path: elastic-certificates.p12
# Create a new cluster with the current node only
# Additional nodes can still join the cluster later
cluster.initial_master_nodes: ["ElasticSearch-Kibana"]
 
# Allow HTTP API connections from anywhere
# Connections are encrypted and require user authentication
http.host: 0.0.0.0
 
# Allow other nodes to join the cluster from anywhere
# Connections are encrypted and mutually authenticated
#transport.host: 0.0.0.0
 
#----------------------- END SECURITY AUTO CONFIGURATION -------------------------

Then, I restart the service using systemctl restart elasticsearch.service. Then I get an error message which directs me to the log file, which indicates that my SSL certificate password is incorrect, but I'm 100% sure that I've typed the SAME password in all of the steps above:

I really don't know what I miss in this configuration.
Please assist.
Thanks

The configuration and error do not match. It seems you haven't configure any password for keystore/truststore used for the HTTP interface. Even though underlyingly it is the same file, you need to configure it separately.

Using @Yang_Wang suggestion, I figured that I've missed 2 commands:

./bin/elasticsearch-keystore add xpack.security.http.ssl.keystore.secure_password
SAME password was entered
./bin/elasticsearch-keystore add xpack.security.http.ssl.truststore.secure_password
SAME password was entered
