Hello,
I've been monitoring the scope occupancy rates of DHCP servers in Zabbix for a long time. For about two months now, I've been encountering an error I can't resolve.
The template I'm using has stopped working. I tried collecting data with a different template, but it still didn't work. I tried manually collecting data using OIDs, but it still didn't work.
I was monitoring the scope via SNMP, and SNMP is enabled. I can retrieve all data from the server using snmpwalk from the terminal. However, when I enter the OID, an error occurs, as shown in the image.

The same error is also occurring in the Zabbix interface.
What worked before no longer works. We've also tested and rolled back server updates, but unfortunately, the results haven't changed.
I look forward to your support on this matter.
Zabbix Version I'm Using: 6.4.21
DHCP Server: Windows 2022
