hi,

I am using putty server . I downloaded ES 2.3.3 and I installed java. After I tried to connection of ES. My ıp number:`187.45.254.52`  
Also I changed network.host:`187.45.254.52` in elasticsearch.yml

```
[root@elasticsearch ~]# service elasticsearch start
Starting elasticsearch (via systemctl): ok

```

After:

`[root@elasticsearch ~]# curl -XGET 'http://187.45.254.52:9200'`

```
{
  "name" : "Coldfire",
  "cluster_name" : "elasticsearch",
  "version" : {
    "number" : "2.3.3",
    "build_hash" : "218bdf10790eef486ff2c41a3df5cfa32dadcfde",
    "build_timestamp" : "2016-05-17T15:40:04Z",
    "build_snapshot" : false,
    "lucene_version" : "5.5.0"
  },
  "tagline" : "You Know, for Search"
}

```

However when I writed on browser `187.45.254.52:9200` but it is not working. I don't understand? It says:

```
This site can not be reached
  187.45.254.52 took too long to respond to the main machine.
Make a search on Google on 187 254 9200
ERR_CONNECTION_TIMED_OUT

```

What is the problem?

My log file:

```

I reinstalled my server.  
I installed java and ES 2.3.3. So I started ES and it worked.  
After I installed Vesta Panel and I try to connect ES. However ES didn't work.  
Why?
