Authentication Error After Configuring SSL

[Emre_Altan]

Hi,
I'm trying to configure ssl and basic authentication in an Amazon EC2 instance. I've installed the elasticsearch, opened authentication by setting xpack.security.enabled to true, and set a password to built-in users with bin/elasticsearch-setup-passwords interactive. It was working nicely, I could access to elasticsearch with my password without any problem. But when I configured the ssl to elastic, it started to not accepting the same password!

I can still access to the elastic if i disable the authentication with ssl. But i also need the authentication.

Moreover, I can authenticate with this curl with http protocol:
curl -u elastic 'http://elastic.mydomain.xyz:9200/_xpack/security/_authenticate?pretty'

But when I use https, it's giving authentication error:
curl -u elastic 'https://elastic.mydomain.xyz:9200/_xpack/security/_authenticate?pretty'

Result:
{ "type" : "security_exception", "reason" : "failed to authenticate user [elastic]", "header" : { "WWW-Authenticate" : [ "Bearer realm=\"security\"", "ApiKey", "Basic realm=\"security\" charset=\"UTF-8\"" ] } }

What's going on? Do you have any ideas? How can i fix it?

-Edit-
My yml settings below:

• network.host: 0.0.0.0

• discovery.seed_hosts: []

• discovery.type: single-node

• xpack.security.enabled: true

• xpack.security.http.ssl.enabled: true

• xpack.security.http.ssl.key: /etc/elasticsearch/ssl/elastic.mydomain.xyz/privkey1.pem

• xpack.security.http.ssl.certificate: /etc/elasticsearch/ssl/elastic.mydomain.xyz/fullchain1.pem

Any suggestions here?

Found the problem. Just added xpack.security.http.ssl.verification_mode: certificate to the elasticsearch.yml and voila! It's working now.
