Question

Zabbix

Good day. I'm trying to connect zabbix agent windows 10
agent log piece:

zabbix agent log

9440:20210725:193728.919 In collect_perfstat()
9440:20210725:193728.929 End of collect_perfstat()
9440:20210725:193729.946 In collect_perfstat()

9440:20210725:193733.985 In collect_perfstat()
9440:20210725:193733.987 End of collect_perfstat()

the call is successful.
Cutting from the log of the zabbix server (received data through a request !!!):

zabbix server log

975:20210725:133930.837 trapper got '{"request":"item.test","data":{"type":"0","proxy_hostid":"0","key":"Temperature.CPU","interface":{"address":"192.168.*.*","port":"10050","type":0}},"sid":"017a5544d64164658cfc79995e8ec5d0"}'
975:20210725:133930.839 In get_value_agent() host:'' addr:'192.168.*.*' key:'Temperature.CPU' conn:'unencrypted'

what to do with this error? In get_value_agent() host:'' addr:'192.168.*.*' key:'Temperature.CPU' conn:'unencrypted'

agent.conf

# This is a configuration file for Zabbix agent service (Windows)

LogFile=C:\Program Files\Zabbix Agent\zabbix_agentd.log

DebugLevel=4

Server=192.168.*.*

Hostname=IT

# TLSConnect=unencrypted
# TLSAccept=unencrypted
UserParameter=Temperature.CPU, C:\OpenHardwareMonitorReport\TemperatureCPU.bat

# TLSConnect=unencrypted
# TLSAccept=unencrypted
Tried to uncomment it - doesn't help. Maybe something to configure on the server itself? The last time on version 5 everything worked fine (in another place).
telnet in both directions OK, agent 5.4.3, ubuntu 20 on the server
