I want to send some nginx logs from fluentd to Elasticsearch , however, fluentd is unable to start due to following error message:

**The client is unable to verify that the server is Elasticsearch. Some functionality may not be compatible if the server is running an unsupported product.**

**[error]: #0 unexpected error error\_class=Elasticsearch::UnsupportedProductError error="The client noticed that the server is not Elasticsearch and we do not support this unknown product."**

This is my fluentd config :

```auto
<source>
  @type tail  
    <parse>    
      @type nginx 
    </parse>  
  path /tmp/lab4/nginx/access.log  
  pos_file /tmp/lab4/nginx/access.po
  tag nginx.access
</source>

<match nginx.**>
 @type elasticsearch
 scheme http
 host 192.168.1.154 
 port 9200 
 with_transporter_log true
 @log_level debug
</match>

```

If I do a curl [http://192.168.1.154:9200](http://192.168.1.154:9200/) , I can see a response from Elasticsearch with the system version and other info .

For reference I am using :

- fluentd version 1.14.5
- fluentd elastic-search-plugin 5.2.0
- elastic-search 7.12.0

Any idea on what I am doing wrong ?
