no network discovery from GUI

[digidax]

Hi there,

from the CLI, I can do successful:

# zabbix_get -s 192.168.130.204 -k net.if.discovery
[{"{#IFNAME}":"lo"},{"{#IFNAME}":"enp5s0"}]

GUI Template is OS Linux, with Network interface discovery rule. Any other stuff like CPU or Memory data are collected successful from this host, exept the network interfaces.
Starting the discovery with "Check now" from GUI, I get the response: Request sent successfully
But status stands at "not supported" and the red "i" with mouse over told: "cannot find the data array in the recives JSON object"

Where do I have to look deeper in the debugging?

Thanks for any hints, Frank

Solved: The new agent on a machine runs with version 4.4.x, the server with 4.2.x

After upgrading the server, discovery workls fine.
