Received empty response from Zabbix Agent at [172.17.113.52]. Assuming that agent dropped connection because of access permissions.

由於我的情況和網上的其他人不一樣，因此這裏記錄下。

我在一臺機器上部署了Zabbix服務器端和Zabbix客戶端

zabbix服務器端是用的docker

客戶端是rpm包安裝的

客戶端配置內設置Server和ServerActive為本機的IP地址172.17.113.52。報了上述的錯誤。查看/var/log/zabbix/zabbix_agentd.log

10352:20181102:194441.382 failed to accept an incoming connection: connection from "10.0.0.3" rejected, allowed hosts: "172.17.113.52"

可以判斷，zabbixserver所在的docker網絡10.0.0.3和本機的172.17.113.52不一致。

##解決辦法
客戶端配置文件中Sever中加上10.0.0.3。
