Elasticsearch cluster not working in swarm (stack) , but works with compose

i have a elasticsearch & kibana docker compose file, which works using docker compose up command, but doesn't work with docker stack deploy command. I have tried using network with overlay driver as well. When i check for cluster health using curl localhost:9200/_cluster/health, i get following error:

{"error":{"root_cause":[{"type":"master_not_discovered_exception","reason":null}],"type":"master_not_discovered_exception","reason":null},"status":503}

version: '3.4'

Removing the port did the trick.

Not sure how the port was causing the issue. If anyone knows details, please share.

Here's the updated working compose:
