Failed to accept an incoming connection: connection from rejected

[al_limelab]

I have been able to get the agent to connect, but over the course of a few minutes the system reports the agent is not reachable.

I have debugging on right now and receiving the following error
"failed to accept an incoming connection: connection from "192.168.200.196" rejected, allowed hosts: "192.168.200.7""

I have verified my ServerActive and Server options and they are correct. I found a few other threads, with this thread relating pretty closely

https://www.zabbix.com/forum/showthread.php?t=51445&highlight=failed+accept+incoming+connection%3A+connection+rejected

However I am not sure how it was fixed as there was nothing to elaborate on the fix.

1.can you post your agent.conf file ?
2.please try to add debug to agent conf and restart agent and post some logs.
3.check at the conf at the server where you have set 192.168.200.7 as allowed host.
4.the reference site you added - they say something about agented.d file
check it and see if you have something overriding your configurations.

/etc/zabbix/zabbix_agentd.d/

I was able to resolve the error about the failed to accept an incoming connection. However now I have a few devices that will not stay connected.

[bbrendon]

The zabbix agent configuration needs the "Server=" setting for remote commands to work. It has to be set to the host that is sending the command.

[zohair.raza]

anyone else looking for a solution:

you can define network range in server settings under agent configuration

Server=192.168.1.0/24,192.168.2.0/24

[vj13]

In /etc/zabbix, there is a directory: zabbix_agentd.d.

Modify the configuration file: zabbix-custom.conf

Server=192.168.200.196
ServerActive=192.168.200.196
Hostname=AWS-135-FS-02
