Agent 2.3.0 running but sever not inventoried.

Hello, everybody,
I have my OCS 2.3.1 server running and working well.
My Windows clients are using agent 2.3.0. and working well.
But I have a PC model that is not inventoried on the server, even though the agent is installed and running, and has a network connection.

The PC is ASUS H110M-R, Intel Core i7-7700, Windows 7 x64 SP1.

This is the OCSInventory.log
