Send HTTP request to localhost

I'm building a Rest API with Flask. The API uses data from Elasticsearch that is running on localhost.

It is possible to send an HTTP request from Flask route to localhost?

Something like this:

@flashlog.route('/checkelasticisup')
def check_elastic_is_up():
    res = requests.get('http://localhost:9200/')
    return jsonify({'message': res.text})

I want to return to the client the Elasticsearch response that you get when you send GET request to localhost:9200:

{
  "name": "wEV_Spx",
  "cluster_name": "elasticsearch",
  "cluster_uuid": "dbPLLgYLRO69iYuT_pp4WA",
  "version": {
    "number": "6.3.0",
    "build_flavor": "default",
    "build_type": "deb",
    "build_hash": "424e937",
    "build_date": "2018-06-11T23:38:03.357887Z",
    "build_snapshot": false,
    "lucene_version": "7.3.1",
    "minimum_wire_compatibility_version": "5.6.0",
    "minimum_index_compatibility_version": "5.0.0"
  },
  "tagline": "You Know, for Search"
}

For now, I'm getting:

Network Error (dns_unresolved_hostname)

How can I send an HTTP request to localhost (I'm using Ubuntu 18.04 LTS)?
Thanks!!

The problem was with my proxy configuration. Didn't configure the correct IP's to ignore. After i added localhost, 127.0.0.1/8 and ::1 to the ignore host field in network settings om my Ubuntu machine, everything works.

As @Metalik said, you must replace localhost with 127.0.0.1 for this to be able to work.
