Hi,  
I installed ES-5.0.0 and java 8 on centos 6.7 server.  
I did changed network.host : **.**.\*\*\*.\*\*\* elasticsearch.yml file but I can't connect ES.  
How can I connect to elastic Search from public ip?

Exactly like you did.

But we can not help you if you don't give details such as logs, config file...

Also check if you have any firewall.

ok,

my elasticsearch.yml file network host setting:

elasticserach.yml file:

```
#network.host: 127.0.0.1
network.host: 95.173.178.186
#
# Set a custom port for HTTP:
#
#http.port: 9200
# ---------------------------------- Network -----------------------------------
#
# Set the bind address to a specific IP (IPv4 or IPv6):
#
#network.host: 127.0.0.1
network.host: **.***. ***.**
#
# Set a custom port for HTTP:
#
#http.port: 9200

```

I restarted elasticsearch.

```

When I start ES It work true :

```
# service elasticsearch start
Starting elasticsearch: [OK] 

```

After I try control:

```
#service elasticsearch status
elasticsearch dead but subsys locked

```

What is the problem?

I'm sorry but you are asking again and again the same question. [Elasticsearch connecition](https://discuss.elastic.co/t/elasticsearch-connecition/65359/9?u=dadoonet)

Is there anything you don't understand in the answers we are giving you?

Yes I know but I'm working on a new server with public ip.  
Also I changed elasticsearch.yml but it didn^t work true so I asked again.

Now:  
I increased in limit.conf file.

[https://www.elastic.co/guide/en/elasticsearch/reference/5.0/\_maximum\_number\_of\_threads\_check.html](https://www.elastic.co/guide/en/elasticsearch/reference/5.0/_maximum_number_of_threads_check.html)

```
@elasticsearch soft nproc 2048

```

It works true . Thank you.  
Best regard.

So before asking you did not read the logs and tried to solve the same issue you have seen and fixed 3 days ago on another server?

Actually I read logs and your response but I didn't uderstand.

..

> But I could not connect again.  
> After I changed Es-5.0.0 elasticsearch.yml file with ES-2.4.1.

I asked again you. Because I didn't understand "Maximum number of threads check setting".  
I hope you can give more detailed information on this subject. That's all.  
Besides i can not explain the subject in english. I am sorry.
