Instead of killing sessions, it resets the counter, but the sessions remain alive

I am using the following configuration:

import sys

c.JupyterHub.services = [
    {
        "name": "jupyterhub-idle-culler-service",
        "command": [
            sys.executable,
            "-m", "jupyterhub_idle_culler",
            "--max-age=0",
            "--timeout=60",
            "--cull-every=15",
            "--concurrency=5",
            "--api-page-size=200",
        ],
        "admin": True,
    }
]
c.JupyterHub.debug_proxy = True
c.ConfigurableHTTPProxy.api_url = 'http://localhost:9009'

c.Jupyterhub.spawner_class = 'jupyterhub.spawner.SimpleLocalProcessSpawner'
c.Spawner.cmd='/usr/local/bin/jupyterhub-singleuser'
c.JupyterHub.port = 9000
c.JupyterHub.hub_ip = '0.0.0.0'
c.JupyterHub.hub_port = 9080

#c.JupyterHub.ssl_key = '/root/ssl/nrfapp'
#c.JupyterHub.ssl_cert = '/root/ssl/nrfapp_new.crt'
c.Authenticator.delete_invalid_users = True
c.Authenticator.admin_users = {'jupyter_admin', 'user'}

c.JupyterHub.authenticator_class = 'ldapauthenticator.LDAPAuthenticator'
c.LDAPAuthenticator.server_hosts = ['my_data']
c.LDAPAuthenticator.server_port = 389
c.LDAPAuthenticator.bind_user_dn = 'CN=my_data,OU=my_data,OU=my_data,DC=my_data,DC=my_data,DC=net'
c.LDAPAuthenticator.bind_user_password = 'my_data'
c.LDAPAuthenticator.user_search_base = 'dc=my_data,dc=my_data,dc=net'
c.LDAPAuthenticator.user_search_filter = '(&(objectCategory=person)(objectClass=user)(sAMAccountName={username}))'
c.LDAPAuthenticator.user_membership_attribute='memberOf'
c.LDAPAuthenticator.group_search_base = 'dc=my_data,dc=my_data,dc=net'
c.LDAPAuthenticator.group_search_filter = '(&(objectClass=group)(memberOf={group}))'
c.LDAPAuthenticator.allowed_groups = ["my_data",]

c.LDAPAuthenticator.allow_nested_groups = True
c.LDAPAuthenticator.create_user_home_dir = True
c.LDAPAuthenticator.create_user_home_dir_cmd = ['adduser','--create-home']

But when the counter counts down the right time, it simply resets the counter, the user's server will remain alive
