```
Error: connect ECONNREFUSED <host>:8200
at Object._errnoException (util.js:992:11)
at _exceptionWithHostPort (util.js:1014:20)
at TCPConnectWrap.afterConnect [as oncomplete] (net.js:1186:14)

```

Trying to setup and connect to APM server on Azure ELK Stack. I installed APM on the kibana VM with the APM server configured to listen on localhost:8200.

I'm testing my NodeJS locally on a server and getting the error above, with host replaced with the public ip. Attempting to change the APM host to the public IP results in a 'too many colons in address' error.

On the VM I have port 8200 open inbound and outbound.

Any help would be appreciated.

Thanks

Hi Scott,

Thanks for trying out Elastic APM. If you are running the NodeJS app on a different machine from the APM Server, you'll need to get APM Server to listen on a public interface. You can do that by starting APM Server with a configuration setting like so:

```
./apm-server -E apm-server.host=0.0.0.0:8200

```

You can also edit the `apm-server.yml` to achieve the same:

```auto
apm-server:
  host: localhost:8200

```

You'll want to familiarize yourself with the security implications of opening up a port to the world: [https://www.elastic.co/guide/en/apm/get-started/master/install-and-run.html#secure-api-access](https://www.elastic.co/guide/en/apm/get-started/master/install-and-run.html#secure-api-access)

best of luck!

The resolution was to mimic the Kibana yml (auto generated with the Azure ELK stack template) and set the following:

```
apm-server:
    host: <Private IP>:8200
```
