<code>curl -GET http://127.0.0.1:9200</code> is the wrong command. 

Try <code>curl -XGET http://127.0.0.1:9200</code>. It should return the short info about your running local node and status 200. If that doesn't work then something else must be wrong.

1) Check what's the status of your port 9200, with <code>lsof</code> command in linux.

In my case following is the result when <code>elasticsearch</code> is started.

<pre><code>prayag@prayag:~$ sudo lsof -i TCP | grep 9200 
chrome 2639 praayg 84u IPv4 116310 0t0 TCP prayag.local:58989-&gt;10.0.4.70:9200 (ESTABLISHED)
chrome 2639 prayag 99u IPv4 116313 0t0 TCP prayag.local:58990-&gt;10.0.4.70:9200 (ESTABLISHED)
java 7634 prayag 141u IPv6 130960 0t0 TCP *:9200 (LISTEN)
</code></pre>

<code>elasticsearch</code> is not a service to me, otherwise to find the port es is running; on I could have checked, 

<pre><code>$ sudo lsof -iTCP -sTCP:LISTEN | grep elasticsearch
</code></pre>

2) check the elasticsearch endpoint

<pre><code>$ curl -IGET http://localhost:9200
HTTP/1.1 200 OK
content-type: application/json; charset=UTF-8
content-length: 327
</code></pre>

<ul>
<li><code>-IGET</code> is equivalent to <code>--head</code> that returns http response headers only.</li>
<li>response <code>200</code> means elasticsearch endpoint is responding properly.</li>
</ul>

Pay attention to memory allocation and usage. In case you let it use unlimited memory it might crash when you least suspect. Here is a tutorial on Elasticseach 5 and Kibana in case anyone else runs into this issue. <a href="https://medium.com/@adnanxteam/how-to-install-elasticsearch-5-and-kibana-on-homestead-vagrant-60ea757ff8c7" rel="nofollow noreferrer">https://medium.com/@adnanxteam/how-to-install-elasticsearch-5-and-kibana-on-homestead-vagrant-60ea757ff8c7</a>

Anyway, I'd try the command:

curl -XGET <a href="http://localhost:9200" rel="nofollow noreferrer">http://localhost:9200</a>

I've recently installed Elasticsearch and everything was working well for the first few days, but somehow today it stopped working

When I start the service, it claims to be fine...

<pre><code>sudo /etc/init.d/elasticsearch start
* Starting Elasticsearch Server
...done.
</code></pre>

But then I get 
<code>curl -GET http://127.0.0.1:9200</code> 
<code>curl: (7) couldn't connect to host</code>

Looking at the elasticsearch logs:

<pre><code>[WARN ][bootstrap ] jvm uses the client vm, make sure to run `java` with the server vm for best performance by adding `-server` to the command line
</code></pre>

Looks like there is a warning regarding the Java VM; could that be the problem? What else should I try/look at?

Can't Connect to Elasticsearch (through Curl)
