Question - Windows Agent

Hello,

I'm using CentOS with Apache and Mariadb.
I deactivated SELinux and Firewalld and now I can access the Physical Machine through the browser xxx.xxx.xxx/ocsreports.
When installing the OCS Windows Agent http://192.168.127.XXX/ocsinventory the machine was not recognized in the 192.168.127.xxx/ocsreports Portal.

Do I need to set something up?
