I'm running logstash docker image 7.5.2 using this configuration file:

```
input {
  beats {
    port => 5044
  }
}

filter {
  mutate {
    add_tag => ["logstash_filter_applied"]
  }
}

output {
  elasticsearch {
    hosts => "elasticsearch:9200"
  }
}

```

However, I'm getting this error message:

```
Error: Address already in use

```

Detailed message:

```
A plugin had an unrecoverable error. Will restart this plugin.

Seems like there’s an existing service using the same port.
