Elasticsearch - Cannot login, WARN received plaintext http traffic on an https channel

I installed elasticsearch 8.5.3 on my Macbook

I also installed logstash 8.5.3 and in its root directory created file simple-config.conf with following content

input {
  file {
    type=>"users-ws-log"
    path=>"/path/to/users-ws.log"
  }
  file {
    type=>"albums-ws-log"
    path=>"/path/to/albums-ws.log"
  }
}

output {
  if [type] == "users-ws-log" {
    elasticsearch {
      hosts => ["localhost:9200"]
      index => "users-ws-%{+YYYY.MM.dd}"
    }
  } else if [type] == "albums-ws-log" {
    elasticsearch {
      hosts => ["localhost:9200"]
      index => "albums-ws-%{+YYYY.MM.dd}"
    }
  }
  stdout { codec => rubydebug }
}

Based on my reading, I should now be able to

  • run elasticsearch with /bin/elasticsearch

, this executed fine and gave me temp 'elastic' user and password

  • go to http://localhost:9200/ and ender 'elastic' user and given password

, but this is not working and all browser shows is

This page isn’t working localhost didn’t send any data. ERR_EMPTY_RESPONSE

, and elasticsearch shows in terminal:

[2022-12-27T15:26:09,914][WARN ][o.e.x.s.t.n.SecurityNetty4HttpServerTransport] [my-MacBook-Pro.local] received plaintext http traffic on an https channel, closing connection Netty4HttpChannel{localAddress=/[0:0:0:0:0:0:0:1]:9200, remoteAddress=/[0:0:0:0:0:0:0:1]:55989}

Solution

  • Figured it out.

    Instead of going to http://localhost:9200/

    , go to https://localhost:9200/

    So, use https instead of http and you will be prompted for user credentials and should be able to login.
