Inventory working only manually

Hello everybody,

I need your help, I installed OCS 2.1.2 on a Windows server and deployed the Windows-client v2.0.3.1.

The clients are correctly installed, when I launch the "run OCS Inventory NG Agent now" I can see the computer on OCS.

I see the pc on OCs but there is no new inventory, I 'm obliged to force it again to have an inventory uptodate...

On the client side, the log are ok :

------------------------------------------------------------

COM SERVER => HTTP Post response received <HTTP Status Code #200>

COM SERVER => Cleaning cURL library

================= TRACE START ===============

================= TRACE STOP ===============

AGENT => Inventory successfully sent

INVENTORY => Writing new inventory state

AGENT => Unloading communication provider

AGENT => Unloading plug-in(s)

AGENT => Execution duration: 00:00:03.

------------------------------------------------------------

On the server I have this :
