Not getting response from Global public IP in Elasticsearch using Debian Server

Elastic Stack Elasticsearch
1

Hi,
I installed elasticsearch on debian server. After installing , I open elasticsearch.yml file for configurations.
I configured these things..

network.host: my global public ip of debian server
http.port : 9200

and I also changed the cluster.name and node.name.

Now whenever I access it using http://myglobalip:9200 in browser , then no response or run query on debian like this
curl -X GET 'http://myglobalip:9200'
then it gives me this error
Failed to connect to myglobalip port 9200: Connection timed out

whenever I change network.host: localhost
It gives me correct result after running this query
curl -X GET 'http://localhost:9200'
its mean that it is working

I search many documents but still my problem not solve.
I also check the port, port is open.

Am I missing something or doing wrong?
kindly help regarding this issue.
regards
AQM

Check your ES logs on startup and make sure it binds to that IP.
Also make sure you don't have a firewall in place.
