    1. Check Local Firewall:
    sudo ufw allow 9200/tcp
sudo ufw reload
    1. Add AWS/Azure Security Groups

    AWS -> EC2 -> Security Groups -> Add an inbound rule for port 9200 with the appropriate source – allow all

    1. Test from a Remote Machine:
    curl http://xx.xxx.xxx.xxx:9200
telnet xx.xxx.xxx.xxx 9200
    1. Elasticsearch Logs
     sudo tail -f /var/log/elasticsearch/elasticsearch.log
