Unable to retrieve version information from Elasticsearch nodes. Request timed out

Hi All,

Elasticsearch is running, but accessing Elasticsearch from the browser it shouldn’t working, the chrome tab should return JSON what I have seen using curl command. I’ll be sharing the JSON that should be displayed in chrome tab but it is returning as site can’t be reached.

curl -XGET http://*.*.*.*:9200/_cluster/health?pretty
{
  "cluster_name" : "fortum-elk",
  "status" : "green",
  "timed_out" : false,
  "number_of_nodes" : 1,
  "number_of_data_nodes" : 1,
  "active_primary_shards" : 2,
  "active_shards" : 2,
  "relocating_shards" : 0,
  "initializing_shards" : 0,
  "unassigned_shards" : 0,
  "delayed_unassigned_shards" : 0,
  "number_of_pending_tasks" : 0,
  "number_of_in_flight_fetch" : 0,
  "task_max_waiting_in_queue_millis" : 0,
  "active_shards_percent_as_number" : 100.0
}

But while running Kibana, it is returning error
