Cannot connect to remote ElasticSearch server

Elastic Stack Elasticsearch
1

I am aware that a similar question was posted back in 2015, but the answers there unfortunately do not help me.

On my remote Windows 10 server (on which Elasticsearch 6.6.2 is installed), I have added an inbound security rule named Port9200:

539×726 52.2 KB

540×727 80.6 KB

I have also added the following lines to my elastisearch.yml file:

transport.host: localhost
transport.tcp.port: 9300
http.port: 9200
network.host: 0.0.0.0

Last but not least, I have ensured that there are no outbound security rules blocking any TCP connection from my local machine to my remote server via Port 9200.

Unfortunately, I am still unable to connect to my remote Elasticsearch server:

1025×566 33.4 KB

What other approaches should I try out, in order to ensure that I can access my remote Elasticsearch server from my local machine?

UPDATE: Here are the results after running netstat -ano | find ":9200":

767×102 39.2 KB

You should change localhost to the machine's IP address and restart elasticsearch

Thanks for your reply. I followed your suggestion, but now I cannot start the ElasticSearch server at all:

if you don't mind, please share the output of ipconfig command here or make sure you are using the right IP address in elasticsearch.yml file.

5

Oh, I also noticed that you set network.host too, please use one only (either transport.host or network.host)

Here is the reference link that you can learn more about it
https://www.elastic.co/guide/en/elasticsearch/reference/current/modules-transport.html

Thanks for your reply. I just tried again, and now I am able to start my remote Elasticsearch server.

This is my IP address, as displayed after running ipconfig:

Here are the updated contents of my elasticsearch.yml file:

transport.host: 10.0.1.4
transport.tcp.port: 9300
http.port: 9200

(I have removed network.host.)

I have restarted my Elasticsearch server remotely, but I am still unable to access it from my local machine.

7

when you are at the remote ES server, can you run this command from the console?
curl -XGET http://10.0.1.4:9200
^ what do you get?

from your local machine, can you run the same command? or use the browser with the URL above?
^ what do you get?

Thanks for your reply. Unfortunately I just left the office and won't return until Monday. I will answer your questions once I get back to work.

Have a great weekend!

No problem.

Hello thn,

I have run the curl command on my remote ES server. Here is the displayed result:

PS C:\Users\M> C:\Users\M\Downloads\curl-7.64.0_3-win64-mingw\curl-7.64.0-win64-mingw\bin\curl.exe -XGET http://10
.0.1.4:9200
{
  "name" : "8F-Edn5",
  "cluster_name" : "elasticsearch",
  "cluster_uuid" : "x7V8Sr8KTRu8_pNixpjOkQ",
  "version" : {
    "number" : "6.6.2",
    "build_flavor" : "default",
    "build_type" : "zip",
    "build_hash" : "3bd3e59",
    "build_date" : "2019-03-06T15:16:26.864148Z",
    "build_snapshot" : false,
    "lucene_version" : "7.6.0",
    "minimum_wire_compatibility_version" : "5.6.0",
    "minimum_index_compatibility_version" : "5.0.0"
  },
  "tagline" : "You Know, for Search"
}

Running the same command on my local machine, this is what I see:

curl: (7) Failed to connect to 10.0.1.4 port 9200: Timed out

Please don't post images of text as they are hardly readable and not searchable.

Instead paste the text and format it with </> icon. Check the preview window.

Thanks @dadoonet, I have edited my post.

13

Thanks. Could you share elasticsearch logs?

14

Are you referring to elasticsearch.log?

15

Yes.

I will split it into multiple posts due to the character limit.

What is your complete elasticsearch.yml file?
