ldap.SERVER_DOWN: Can't contact LDAP server. The TLS connection was non-properly terminated

Question

I am trying to deploy OpenID Connect for my openstack instances [vmware host ubuntu 20.04, instances are also same]. The overall goal is to create a cyber range this and using pre-build scripts. While executing one of the playbooks I am continuously getting ldap.Server_Down error. The yml file is

- name: Ensure ou for users
  community.general.ldap_entry:
    dn: ou=people,dc=springframework,dc=org
    objectClass:
      - top
      - organizationalUnit
    bind_dn: cn=Directory\ Manager
    bind_pw: "{{ kypo_crp_oidc_local_provider_ldap_root_password }}"
    server_uri: ldaps://localhost:1636
    validate_certs: False
  register: ldap_entry
  until: ldap_entry is not failed
  retries: 30
  delay: 5

And the output is

TASK [kypo-crp-local-oidc : Ensure ou for users] *******************************************************
FAILED - RETRYING: Ensure ou for users (30 retries left).
FAILED - RETRYING: Ensure ou for users (29 retries left).
....
FAILED - RETRYING: Ensure ou for users (1 retries left).
An exception occurred during task execution. To see the full traceback, use -vvv. The error was: ldap.SERVER_DOWN: {'result': -1, 'desc': "Can't contact LDAP server", 'errno': 107, 'ctrls': [], 'info': 'The TLS connection was non-properly terminated.'}
fatal: [kypo]: FAILED! => {"attempts": 30, "changed": false, "details": "{'result': -1, 'desc': \"Can't contact LDAP server\", 'errno': 107, 'ctrls': [], 'info': 'The TLS connection was non-properly terminated.'}", "msg": "Cannot bind to the server."}

After adding more verbosity to the command in few tries it also generate message saying invalid credentials

FAILED - RETRYING: Ensure ou for users (23 retries left).Result was: {
    "attempts": 8,
    "changed": false,
    "details": "{'msgtype': 97, 'msgid': 1, 'result': 49, 'desc': 'Invalid credentials', 'ctrls': []}",

            "dn": "ou=people,dc=springframework,dc=org",
            "objectClass": [

            ],

            "validate_certs": false
        }
    },
    "msg": "Cannot bind to the server.",
    "retries": 31
}

while most of the tries output following error:

 FAILED - RETRYING: Ensure ou for users (26 retries left).Result was: {
"attempts": 5,
"changed": false,
"details": "{'result': -1, 'desc': \"Can't contact LDAP server\", 'errno': 107, 'ctrls': [], 'info': 'The TLS connection was non-properly terminated.'}",

            "bind_pw":

            "dn": "ou=people,dc=springframework,dc=org",
            "objectClass": [
                "top",
                "organizationalUnit"
            ],
            "params": null,
            "server_uri": "ldaps://localhost:1636",
            "start_tls": false,
            "state": "present",
            "validate_certs": false
        }
    },
    "msg": "Cannot bind to the server.",
    "retries": 31
}

The port 1636 is in listening mode when checked

root@kypo-head:/home/ubuntu# netstat -lt

Cant it be the problem that yml file is accessing server URI as ldaps://localhost:1636 while the opened connections shows localhost:1636?
