Kibana https ssl crt not working

Elastic Stack Kibana
1

Hi All,
i am facing an issue converting my Kibana url to a secured url.

Here's what i did:
Method 1:

  1. created a .csr and .key file in my elastic cluster.
  2. provided this .csr and .key file to my certificate team and received the .crt file.
  3. Moved these files to kibana server and Provided the path of .crt and .key file in kibana.yml after enabling the ssl.
  4. saved and restarted the server.

Error: Site cannot be reached.

Method 2:

  1. Created a .csr with the IIS in my kibana server.
  2. provided this .csr and .key file to my certificate team and received the .crt file.
  3. Moved these files to kibana server and Provided the path of .crt file in kibana.yml after enabling the ssl. No Key was given.
  4. Restarted the service.

Error: Site cannot be reached.

Method 3:

  1. after creating a .csr and .key from elastic cluster, i used a open ssl command to generate a self signed certificate.

Error: URL worked but it was not secure.

Kibana .yml:

# Kibana is served by a back end server. This setting specifies the port to use.
server.port: 443

# Specifies the address to which the Kibana server will bind. IP addresses and host names are both valid values.
# The default is 'localhost', which usually means remote machines will not be able to connect.
# To allow connections from remote users, set this parameter to a non-loopback address.
server.host: "10.166.75.201"

# Enables you to specify a path to mount Kibana at if you are running behind a proxy.
# Use the `server.rewriteBasePath` setting to tell Kibana if it should remove the basePath
# from requests it receives, and to prevent a deprecation warning at startup.
# This setting cannot end in a slash.
#server.basePath: ""

# Specifies whether Kibana should rewrite requests that are prefixed with
# `server.basePath` or require that they are rewritten by your reverse proxy.

# If your Elasticsearch is protected with basic authentication, these settings provide
# the username and password that the Kibana server uses to perform maintenance on the Kibana

# is proxied through the Kibana server.
elasticsearch.username: "kibana"
elasticsearch.password: "e@13"

# Enables SSL and paths to the PEM-format SSL certificate and SSL key files, respectively.
# These settings enable SSL for outgoing requests from the Kibana server to the browser.

# server.ssl.key: D:\kibana-7.2.0-windows-x86_64\Kibana-cert\kibana-cert.key
# Optional settings that provide the paths to the PEM-format SSL certificate and key files.

#ops.interval: 5000

# Specifies locale to be used for all localizable strings, dates and number formats.
#i18n.locale: "en"

What should i do to have a secured connection, I have to do some tweaks in my method 1 or 2.
Guide me on my resolution!

Thanks!

Hi @katara

Please add more details on how do you generate cert, e.g. the command

You can also check elasticsearch-certutil and documentation on how to secure the cluster

Hi @Dzmitry,
I did utilise the elasticsearch-certutil to create the .csr and . key files.
Later I created the self signed.crt with

> openssl req -x509 -sha256 -nodes -days 365 -newkey rsa:2048 -keyout privateKey.key -out certificate.crt

However, this generates a certificate that's not secured, yet the url works.

My organization has a pki system which got me a certificate created by them using the csr I provided. Not sure how they create a certificate from their end.
I can however check with them and update.

Thanks!
Katara
