Filebeat not able to connect to kibana hosted in another server

Elastic Stack Beats
1

Hi, I have hosted elasticsearch and kibana in one server and filebeat and my application in another server. I want to send my application logs to elasticsearch via filebeat. I have configured my filebeat.yml to IP of elasticsearch and kibana. When i do curl GET on elasticsearch, im getting proper response, but to kibana i'm getting error as "curl: (35) error:0A00010B:SSL routines::wrong version number"

Also when i do "./filebeat setup -e" i'm getting below error.

"message":"Exiting: error importing Kibana dashboards: fail to import the dashboards in Kibana: Error importing directory <path to elk_stack>/elk_stack/filebeat-8.14.3-linux-x86_64/kibana: failed to import Kibana index pattern: 1 error: error loading index pattern: returned 413 to import file: error extracting JSON for error response: invalid character '<' looking for beginning of value.

Hi @Nanditha

Share your filebeat.yml please.

How did you install elasticsearch and Kibana

Hi @stephenb, thank you for your replay.

I have installed elasticsearch and kibana via debian package, referring to below official elasticsearch links.

one more thing I missed mentioning in my previous post, my elastic and kibana is in AWS EC2 instance and my filebeat is inside a docker container. I have allowed all/any connection to my container using this command,
docker run -it --net=host imageid bash

Here is my filebeat.yml :

# ============================== Filebeat inputs ===============================

filebeat.inputs:
- type: log
  id: my-filestream-id

  multiline.negate: true

Looks like you're running an nginx proxy in front of kibana. I suspect that may be your issue here. You'll want that setup to go directly to Kibana.

Hi @stephenb,
Can you please help me with the steps/any website i can refer to, if you know.

Steps for what?

In filebeat.yml you need to set

Directly to the Kibana host port....

Thank you. The issue is resolved. I disabled nginx and set my kibana port to default(5601) and updated same in my filebeat.yml. Everything works now.
