Logstash connection doesn't work [connection-problem]

You may have configured {{ls}} or Auditbeat incorrectly. To resolve the issue:

Make sure that {{ls}} is running and you can connect to it. First, try to ping the {{ls}} host to verify that you can reach it from the host running Auditbeat. Then use either nc or telnet to make sure that the port is available. For example:
shell
```
ping <hostname or IP>
telnet <hostname or IP> 5044
```
Verify that the config file for Auditbeat specifies the correct port where {{ls}} is running.
Make sure that the {{es}} output is commented out in the config file and the {{ls}} output is uncommented.
Confirm that the most recent Beats input plugin for {{ls}} is installed and configured. Note that Beats will not connect to the Lumberjack input plugin. To learn how to install and update plugins, see Working with plugins.
