On your local machine try:

```auto
curl -XGET http://127.0.0.1:9200
curl -XGET http://localhost:9200

```

You can also change:

```
network.host: 0.0.0.0

```

to

```
network.host: 10.0.1.4

```

And restart the node  
Note that you won't be able to use `localhost` or `127.0.0.1` but only `10.0.1.4`.

Thanks for your reply. After changing

```auto
network.host: 0.0.0.0

```

to

```auto
network.host: 10.0.1.4

```

I see the following when running `curl -XGET http://localhost:9200`:

`curl: (7) Failed to connect to localhost port 9200: Connection refused`

Before that change, I saw the following instead:

```

I still cannot access the remote server from my local machine, even with the changes.

</div>

Just to be clear, when I run the command `curl -XGET http://10.0.1.4:9200` from my **local machine** , I see this:

`curl: (7) Failed to connect to 10.0.1.4 port 9200: Timed out`

When I run the command `curl -XGET http://10.0.1.4:9200` on my **remote ES machine** itself, I see this:

```auto
{
  "name" : "8F-Edn5",
  "cluster_name" : "elasticsearch",
  "cluster_uuid" : "x7V8Sr8KTRu8_pNixpjOkQ",

```

And when I run `curl -XGET http://localhost:9200` on my **remote ES machine** , I also see this:

`curl: (7) Failed to connect to 10.0.1.4 port 9200: Timed out`

This is **after** changing

```auto
network.host: 0.0.0.0

```

to

```auto
network.host: 10.0.1.4

```

The logs you just pasted are happening at `10:30`.  
The previous logs were at `11:21`.

Out of curiosity I ran `curl XGET` on my local machine with my remote ES server's WAN IP address. I also received `curl: (7) Failed to connect to [WAN IP address] port 9200: Timed out`.

I am suspicious of that `bound_addresses {[::]:9200}` message. On Linux I think this means it's listening on every interface for both IPv4 and IPv6 traffic, but I'm not sure that's the case on Windows. Could you set `http.bind_host: 10.0.1.4` to override this too?

I also don't see any evidence yet that there's _any_ connectivity between your local and remote machines on this address. Can you provide some evidence of this?

That is correct -- I cannot access Port 9200 on that address from my local machine.

Sure, but can you access anything at all on that machine from your local machine using the address `10.0.1.4`? This is not a public IP address: addresses of the form `10.x.x.x` [are not routable across the internet](https://en.wikipedia.org/wiki/Private_network). I am interested in narrowing the problem down to either Elasticsearch or to your network config.

Miao: is this "remote server" you have been trying to get to from your local machine is a VM (virtual machine) running in your local machine or other machine? if not, are your machine and the remote server on the same network? so far, we can tell that elasticsearch was started properly... the problem is from your local machine to this remote server.

Hello @DavidTurner and @thn, thanks for your replies! To answer your questions:

> [@thn](#):
>
> is this "remote server" you have been trying to get to from your local machine is a VM (virtual machine) running in your local machine or other machine?

The remote server is a VM running on another machine.

> [@thn](#):
>

They do not belong on the same network.

No.
