An error occurred curl: (52) Empty reply from server

Elastic Search

Good day, a problem arose when requesting the following address: curl -X GET "http://localhost:9200" an error occurs curl: (52) Empty reply from server. The code for connecting to the elasticsearch service is launched from the Docker container:

elasticsearch:
 container_name: elasticsearch_container
 image: docker.elastic.co/elasticsearch/elasticsearch:8.15.3
 restart: always
 environment:

 kibana:
 container_name: kibana_container
 image: docker.elastic.co/kibana/kibana:8.15.3
 restart: always
 environment:
 - ELASTICSEARCH_HOSTS=["http://elasticsearch_container:9200"]
 ports:
 - 5601:5601
 networks:
 - elastic
 volumes:
 - ./kibana.yml/:/usr/share/kibana/config/kibana.yml:ro
 depends_on:
 - elasticsearch

For some reason, the elasticsearch-data directory is empty and the console displays errors:

failed to obtain node locks, tried [/usr/share/elasticsearch/data]; maybe these locations are not writable or multiple nodes were started on the same data path?
...
Caused by: java.nio.file.NoSuchFileException: /usr/share/elasticsearch/data/node.lock
...
Caused by: java.nio.file.AccessDeniedException: /usr/share/elasticsearch/data/node.lock

You have a volume / permissions / paths error etc...

Try absolute paths, make sure docker user has permissions to ready write... that is what the error is telling you...

Also when you mess up a volume it can create a bad file or directory that needs to be cleaned up...

BTW this is my single node node security

In other compose were I want to maintain the volume
