Logstash refusing connection error

Elastic Stack Logstash
1

Hi All,

I'm trying to connect to Kibana after running the logstash but could see that the connection is getting refused after running the file.
Following are the responses on batch.
Could you please let me know when and why does this error occur.

HI @vaishalik03, Welcome to the Elastic community.

Could you first try to connect with curl command from the same machine ? Let's make sure there is no firewall blocker or any.

  1. firewall, opened port 9200,
  2. network.host: 0.0.0.0 in elasticsearch.yml
  3. Check does ES use http or https- http://a0310pnpbiapp02:9200/
