I have installed `apm-server` and setup apm-server.yml as bellow for nodeJs Agent

```auto
output.elasticsearch:
  hosts: ["localhost:9200"]
  username: "elastic"
  password: "elastic"

```

then run service apm-server start .

configured Node side as bellow

```auto
var apm = require('elastic-apm-node').start({
    serviceName: 'MyApp',
    serverUrl: 'http://localhost:8200'
  })

```

Checked status

**APM Server status : You have correctly setup APM Server**

**Agent status : Data successfully received from one or more agents**

It's worked last night and showed charts on kibana dashboard.but now i'm getting bellow error on my Console and No services found on dashboard

`[ERROR] APM Server transport error (ECONNREFUSED): connect ECONNREFUSED 127.0.0.1:8200`

Kibana - 7.3.1  
apm-server - 7.3.1

I have checked `apm-server` logs directory.but there is no any log file.

and tried `curl -i http://localhost:8200`.it's says  
`curl: (7) Failed to connect to localhost port 8200: Connection refused`.

Hi,

Is the process running? what does `ps -ef | grep apm-server` say?

If it is not running, can you try `sudo -u apm-server apm-server -e` ? What does stdout/stderr say?

Thank you @jalvz. `sudo -u apm-server apm-server -e` worked for me.

Glad to hear! You initially mentioned that `service apm-server status` was showing an error. If you kill that `sudo -u apm-server apm-server -e` and try again with `server apm-server start`, does it work?  
Do you find a log file `/var/log/apm-server/apm-server` ?
