Faraday::ConnectionFailed: Connection refused - GitLab EE with elasticsearch

Elasticsearch is enabled in Admin settings with localhost:9200

I am trying to enable and use elasticsearch with GitLab. Elasticsearch is started, get this from localhost:9200,

{
  "name" : "TTTTTT",
  "cluster_name" : "elasticsearch",
  "cluster_uuid" : "tj4sads12P-_32432csad23",
  "version" : {
    "number" : "5.6.5",
    "build_hash" : "6a37571",
    "build_date" : "2017-12-04T07:50:10.466Z",
    "build_snapshot" : false,
    "lucene_version" : "6.6.1"
  },
  "tagline" : "You Know, for Search"
}

But when run the 1st command to start with gitlab-rake gitlab:elastic:create_empty_index following this guide https://docs.gitlab.com/ee/integration/elasticsearch.html:

which seems odd, unless there is something missing.

gitlab-rake gitlab:check returns this for elasticsearch:
