Getting 'missing auth credentials' after setting SSL in Elasticsearch

[tmporary]

Hi,

Recently I set up ssl for HTTP and TCP in elasticsearch but I'm constantly getting below error when trying to call elastic API

curl -k --cert MY_CERT.pem:Password 'https://localhost:9200/_xpack/security/_authenticate?pretty'

Error:

 "error" : {
    "root_cause" : [
      {
        "type" : "security_exception",
        "reason" : "missing authentication credentials for REST request [/_xpack/security/_authenticate?pretty]",
        "header" : {
          "WWW-Authenticate" : [
            "Bearer realm=\"security\"",
            "ApiKey",
            "Basic realm=\"security\" charset=\"UTF-8\""
          ]
        }
      }
    ],
    "type" : "security_exception",
    "reason" : "missing authentication credentials for REST request [/_xpack/security/_authenticate?pretty]",
    "header" : {
      "WWW-Authenticate" : [
        "Bearer realm=\"security\"",
        "ApiKey",
        "Basic realm=\"security\" charset=\"UTF-8\""
      ]
    }
  },
  "status" : 401
}

Elastic config:

cluster.name: local_test_cluster

node.name: master_main

network.host: 0.0.0.0

bootstrap.memory_lock: true

node.master: true
node.data: false

discovery.seed_hosts: localhost:9300

cluster.initial_master_nodes: master_main

xpack:
  security:
    enabled: true
    transport:
      ssl:
        enabled: true
        verification_mode: certificate
        keystore:
          path: certs/cert.p12
          password: xyz
          type: PKCS12
        truststore:
          path: certs/cert.p12
          password: xyz
          type: PKCS12
    http:
      ssl:
        enabled: true
        verification_mode: certificate
        client_authentication: optional
        keystore:
          path: certs/cert.p12
          password: xyz
          type: PKCS12
        truststore:
          path: certs/cert.p12
          password: XYZ
          type: PKCS12
  monitoring:
    enabled: true

I've tried running:

bin/elasticsearch-setup-passwords interactive

and then

curl -k --cert MY_CERT.pem:PASWORD -u elastic:password 'https://localhost:9200/_xpack/security/_authenticate?pretty'

but then I'm getting:

{
  "error" : {
    "root_cause" : [
      {
        "type" : "security_exception",
        "reason" : "failed to authenticate user [elastic]",
        "header" : {
          "WWW-Authenticate" : [
            "Bearer realm=\"security\"",
            "ApiKey",
            "Basic realm=\"security\" charset=\"UTF-8\""
          ]
        }
      }
    ],
    "type" : "security_exception",
    "reason" : "failed to authenticate user [elastic]",
    "header" : {
      "WWW-Authenticate" : [
        "Bearer realm=\"security\"",
        "ApiKey",
        "Basic realm=\"security\" charset=\"UTF-8\""
      ]
    }
  },
  "status" : 401
}

Even if that worked then Id have to do this in my target environment where elastic is deployed and I cannot do that. Can someone help on this one?
