I have installed and run ECK 8.7.1 with fleet:

```auto
$ k get agent

fleet-server green 3 3 8.7.1 84m

```

**Kibana version** : 8.7.1

**Elasticsearch version** : 8.7.1

**APM Server version** : 8.7.1

**APM Agent language and version** : Node.JS `"elastic-apm-node": "^3.45.0",`

**Browser version** : chrome

**Original install method (e.g. download page, yum, deb, from source, etc.) and version**:

My application config:

```auto
var apm = require('elastic-apm-node').start({
  // Override service name from package.json
  // Allowed characters: a-z, A-Z, 0-9, -, _, and space
  serviceName: 'myapplication-apm',
  // Use if APM Server requires a token
  secretToken: '',
  // Use if APM Server uses API keys for authentication
  apiKey: '',
  // Set custom APM Server URL (default: http://127.0.0.1:8200)
  serverUrl: '',
  // Only activate the agent if it's running in production
  active: process.env.NODE_ENV === 'production'
})

```

My application log:

```auto
{"log.level":"error","@timestamp":"2023-05-05T07:42:34.295Z","log":{"logger":"elastic-apm-node"},"ecs":{"version":"1.6.0"},"message":"APM Server transport error (ECONNREFUSED): connect ECONNREFUSED 127.0.0.1:8200"}

Hi @khteh,

It looks like your APM agent is trying to connect to the default APM server URL. Can you check the address where your APM server is running and that it matches the value of the `serverUrl` property in your agent config?

I'm assuming the issue was the serverUrl wasn't specified and therefore picking up the default, so the new config would look something like the below:

```auto
var apm = require('elastic-apm-node').start({
  // Override service name from package.json
  // Allowed characters: a-z, A-Z, 0-9, -, _, and space
  serviceName: 'myapplication-apm',
  // Use if APM Server requires a token
  secretToken: '',
  // Use if APM Server uses API keys for authentication
  apiKey: '',
  // Set custom APM Server URL (default: http://127.0.0.1:8200)
  serverUrl: 'http://my-apm-server:8200',
  // Only activate the agent if it's running in production
  active: process.env.NODE_ENV === 'production'
})

```

@khteh if that's not indeed the solution do let us know!

Yes, setting `serverUrl` and `verifyServerCert: false` is the solution. Thanks.
