I'm installing elasticsearch, kibana and fluentd in kubernetes with helm chart Elasticsearch and kibana pods stand up smoothly, but fluentd pods don't stand up I get the following errors:

```auto

```

**command for elasticsearch**  
`helm install elasticsearch-master elastic/elasticsearch -n efk`  
**command for fluentd**  
`helm install fluentd fluent/fluentd --set elasticsearch.password=22qz66p1gsr8ELA1 -n efk`  
**command for kibana**  
`helm install kibana elastic/kibana -n efk`

**elasticsearch image:**

```
Image: docker.elastic.co/elasticsearch/elasticsearch:8.5.1
Ports: 9200/TCP, 9300/TCP
Host Ports: 0/TCP, 0/TCP

```

**kibana image:**

```
  Image: docker.elastic.co/kibana/kibana:8.5.1
    Port: 5601/TCP
    Host Port: 0/TCP

```

**fluentd image:**

```
Image: fluent/fluentd-kubernetes-daemonset:v1.15.2-debian-elasticsearch7-1.0
Port: 24231/TCP
Host Port: 0/TCP

```

fluentd config map elasticsearch output

```auto
04_outputs.conf: |-
    <label @OUTPUT>
      <match **>
        @type elasticsearch
        host elasticsearch-master
        port 9200
        path ""
        user elastic
        password 22qz66p1gsr8ELA1
      </match>
    </label>

```

How can I fix
