Docker Image for Elastic search version 8.8.0 not connecting with the Application that has same Elasticsearch version

### Description

Hi
I am running elasticsearch server of version 8.8.- using docker image. Now, I am trying to access this elastic search server from my application which is running in another docker image as below:

ELASTIC_SEARCH_SERVER = "http://host.docker.internal:9200"
db = Elasticsearch(ELASTIC_SEARCH_SERVER)

So, I tried to debug this further by executing below command from inside my application docker container:
curl http://host.docker.internal:9200

Please let me know if there are any known issues here.
