SNMP - Can't get snmp datas

Dear Staff,

I have actually the ocs inventory installed in my debian webserver,
I would love to use all the network functions,
The ip discovery is helping me a lot,

I also would like to use the SNMP Tool, but I can't get datas on snmp table,

I don't know why, but no data appears on snmp ocs area, The table is empty,

I tried to install snmp tools(Net-Tools) on debian, tried to request snmp info through snmpwalk on server and it is working fine,
If I am sure, heard that the ocs agents has the function to get the snmp info around the subnet, I also checked the file "C:\ProgramData\OCS Inventory NG\Agent\snmplist.txt" and there are a lot of devices written there,

Idk if it's a server communication trouble or else,

Please, Could you help me figure out why there is no snmp devices on snmp ocs function ?

Thanks a lot

Bests Regards,

Matheus Pavanetti
