Hardware, Network, Devices are empty

Hello,

We are running OCS 2.8.1 latest (26/01/2021) and there is empty information in Hardware, Network and Devices for all new computer.

No error in apache and mariadb

I set mariadb debug mode to check SQL inssert query. The query is good, but empty:

                  494 Query     INSERT INTO networks(`HARDWARE_ID`,`TYPEMIB`,`IPGATEWAY`,`IPMASK`,`VIRTUALDEV`,`STATUS`,`MACADDR`,`SPEED`,`TYPE`,`IPDHCP`,`IPSUBNET`,`MTU`,`DESCRIPTION`,`IPADDRESS`) VALUES('143195','','','','','','','','','','','','','')

The software table has data.

Thanks
