no active checks on server [10.23.xxx.xxx:10051]: host not found

[niteshsinghal88]

Hi,

I have installed zabbiz master and agent inside docker container.
I configured the agent in the zabbiz UI but it always showing "Zabbix agent on zabbiz_test_agent is unreachable for 5 minutes".
I checked the logs on agent server and it says "no active checks on server [10.23.xxx.xxx:10051]: host [10.23.xxx.xxx] not found".

I went through multiple topics on the same issue but that didn't help me.

https://www.zabbix.com/forum/zabbix-help/12303-using-active-checks-vs-passive-checks

Master server hostname: usxxxxx523
IP: 10.23.xxx.xxx


On Agent side:
I have attached the zabbix_agentd.conf in this thread.

Also, everytime I try to make changes in zabbix_agentd.conf and restart docker container on agent, but all my changes seem to be rollback and does not apply. It this something which is already hard-coded in the docker image?
I used the official zabbix documentation to install dockerize zabbix installation.

I'd really appreciate any advise on this issue.

Thanks,
Nitesh

did you try to remove the port number from the server ip ?

Did you change items type from "zabbix agent" to "zabbix (active) agent" on that host?
