hello all, when I configured (http.host: 192.168.170.146) in the elasticsearch.yml file, and comment the network.host part, elasticsearch can be started with no problem. And, I can see all the logs that filebeat ships to elasticsearch in the Kibana console. But, when I used network.host instead of http.host in the elasticsearch.yml as following, elasticsearch can not be started network.host: 192.168.170.146 and following messages are shown in the logs. could you please advise me?

when i used http.host, everything is OK and this error doesn't exist. it is weird, why when i used network.host, the error appears? ---

Setting the `network.host` to something other than localhost [triggers production mode](https://www.elastic.co/guide/en/elasticsearch/reference/6.4/bootstrap-checks.html), which enables the bootstrap checks that report the error you are seeing. ---

I have two questions: 1- I want to define a cluster; actually, I have two elascticsearch nodes and want to define a cluster according to these nodes. can I do this with using http.host insead of network.host in elasticsearch.yml? 2- I do all tasks mentioned in the link, but yet I can see the same error. what should I do? ---

No. Elasticsearch nodes do not communicate internally over HTTP, but rather use the transport protocol. > [@sahere37](#): > > 2- I do all tasks mentioned in the link, but yet I can see the same error. what should I do? There are a number of bootstrap checks, so make sure you have covered all of them. ---
