Exception message in IPsec VPN for Business module configuration

Good afternoon.

I installed the IPsec VPN for Business module and in the configuration I got the following message:

Ooooops: exception 'clearos\apps\base\Engine_Exception' with message '000 using kernel interface: netkey' in /usr/clearos/apps/base/libraries/Shell.php:227 Stack trace: #0 /usr/clearos/apps/static_vpn/libraries/Openswan.php(582): clearos\apps\base\Shell->execute('/usr/sbin/ipsec', 'auto --status', true, Array) #1 /usr/clearos/apps/static_vpn/controllers/report.php(73): clearos\apps\static_vpn\Openswan->get_tunnel_status() #2 /usr/clearos/framework/application/libraries/Page.php(641): Report->index() #3 /usr/clearos/framework/application/libraries/Page.php(504): Page->view_controllers(Array, 'Static IPsec VP...') #4 /usr/clearos/apps/static_vpn/controllers/static_vpn.php(76): Page->view_forms(Array, 'Static IPsec VP...') #5 [internal function]: Static_Vpn->index() #6 /usr/clearos/framework/system/core/CodeIgniter.php(535): call_user_func_array(Array, Array) #7 /usr/clearos/framework/htdocs/app/index.php(224): require_once('/usr/clearos/fr...') #8 {main}

I am very grateful if any of you can help me by indicating how I can correct this or what happened.
