curl: (7) Failed to connect to localhost port 9200: Connection refused. Even after having configured /etc/elasticsearch/elasticsearch.yml - elasticsearch

I am trying to check if elasticsearch is properly working on Ubuntu 14.04. So for that, I am running following commands:
$ sudo service elasticsearch start
$ curl -X GET 'http://localhost:9200'
Error:
curl: (7) Failed to connect to localhost port 9200: Connection refused
I am attaching screenshot of my /etc/elasticsearch/elasticsearch.yml file here and also attaching my-application.log

The problem is pretty evident from the log file
org.elasticsearch.ElasticsearchException: X-Pack is not supported and Machine Learning is not available for [linux-x86]; you can use the other X-Pack features (unsupported) by setting xpack.ml.enabled: false in elasticsearch.yml
Simply add this to your elasticsearch.yml config file and restart the service
xpack.ml.enabled: false

Elasticsearch not able to connect to port 9200

After setting up elasticsearch and kibana, I installed curl.
I tried running this command on terminal:
curl -X GET https://localhost:9200
And it is giving this error.
curl: (7) Failed to connect to localhost port 9200 after 6 ms: Couldn't connect to server
Does anyone know how to resolve this issue?

cURL error 28: Failed to connect to systemb port 80: Timed out for http://systemb/api/push_products [duplicate]

This question shows research effort; it is useful and clear
I have checked the cURL not working properly
When I run the command curl -I https://www.example.com/sitemap.xml
curl: (7) Failed to connect
Failed to connect on all port
this error only on one domain, all other domain working fine, curl: (7) Failed to connect to port 80, and 443
Thanks...
First Check your /etc/hosts file entries, may be the URL which You're requesting, is pointing to your localhost.
If the URL is not listed in your /etc/hosts file, then try to execute following command to understand the flow of Curl Execution for the particular URL:
curl --ipv4 -v "https://example.com/";
After many search, I found that Hosts settings not correct
Then I check nano /etc/hosts
The Domain point to wrong IP in hosts file
I change the wrong IP and its working Fine
This is new error Related to curl: (7) Failed to connect
curl: (7) Failed to connect
The above error message means that your web-server (at least the one specified with curl) is not running at all — no web-server is running on the specified port and the specified (or implied) port. (So, XML doesn't have anything to do with that.)
you can download the key with browser
then open terminal in downloads
then type sudo apt-key add <key_name>.asc
Mine is Red Hat Enterprise(RHEL) Virtual Machine and I was getting something like the following.
Error "curl: (7) Failed to connect to localhost port 80: Connection refused"
I stopped the firewall by running the following commands and it started working.
sudo systemctl stop firewalld
sudo systemctl disable firewalld
If the curl is to the outside world, like:
curl www.google.com
I have to restart my cntlm service:
systemctl restart cntlm
If it's within my network:
curl inside.server.local
Then a docker network is overlapping something with my CNTLM proxy, and I just remove all docker networks to fix it - you can also just remove the last network you just created, but I'm lazy.
docker network rm $(docker network ls -q)
And then I can work again.

What port does elasticsearch listen on when installed via homebrew?

I'm using Mac 10.13.6. I just installed elasticsearch via homebrew and launched it ...
brew services start elasticsearch
Service `elasticsearch` already started, use `brew services restart elasticsearch` to restart.
In my /usr/local/etc/elasticsearch/elasticsearch.yml configuration file, I have
http.port: 9200
However, when I attempt to see if that port is available, I get a connection refused ...
localhost:tmp davea$ telnet localhost 9200
Trying ::1...
telnet: connect to address ::1: Connection refused
Trying 127.0.0.1...
telnet: connect to address 127.0.0.1: Connection refused
telnet: Unable to connect to remote host
What port is elasticsearch getting launched on and how can I change that?
That may be the problem of Mac firewall? Edit elasticsearch.yml file in elasticsearch/config folder. Change the localhost to 127.0.0.1 to take a try?
network.host: 127.0.0.1
#
# Set a custom port for HTTP:
#
http.port: 9200

Connection refused with ElasticSearch on Digital Ocean

I install Elastic Search using this tutorial changing only version by Elastic Search.
Set network.host: 127.0.0.1 to access by terminal. But show this error when try connect:
curl: (7) Failed to connect to localhost port 9200: Connection refused
Check your port 9200 is open or not, then check if you're not using the UFW firewall.
In case of you are using the UFW firewall :
sudo ufw allow 9200

ElasticSearch installation error - curl: (7) Failed connect to localhost:9200; Connection refused

I'm trying to configure ElasticSearch with this tutorial
I did everything except step 4 of the tutorial.
In step 5, when I run this command:
curl -X GET 'http://localhost:9200'
I get this error:
curl: (7) Failed connect to localhost:9200; Connection refused
I have tried two different things to fix the error:
network.bind_host: 0.0.0.0
network :
host : 192.168.2.229
But neither solved the problem.
What should I do to test Elasticsearch and solve this error?
Thanks.
You just have to uncomment these lines in your elastic-search configuration file:
cluster.name: your_cluster_name
node.name: "Your Node Name"
network.bind_host: localhost
network.publish_host: 0.0.0.0
network.host: 0.0.0.0
run this command.
curl -X GET http://localhost:9200
