    Received empty response from. Assuming agent dropped connection access permissions.

    Hello,



    After installing a Zabbix server and a Zabbix Proxy with an agent running on both machines, the server seems to not be able to get data from the agent on both the server and the proxy. I get the following error on the server: "Received empty response from Zabbix Agent at 192.168.x.x. Assuming that agent dropped connection because of access permissions."



    This is my current configuration:

    I have Docker running on 2 Debian 10 machines both in the same network. On one machine, I have installed the Zabbix Server with the official Docker-compose from Zabbix (the newest one) in different Docker containers and on the other I have installed the Zabbix Proxy with the official images from Zabbix in different Docker containers. On both of these machines I have an agent running, but the agent is running on the host OS (Debian 10) and not in a Docker container. I tried to make it work with both zabbix-agent and zabbix-agent2 but changing agent types didn't help either. The agents that im using are running the same version of Zabbix as the Zabbix Server and Proxy.



    The strange thing is that when I install the zabbix-agent on a Windows 10 machine, and configure it so that it sends its data to the Proxy server and then to the server, it works just fine as my proxy is working and connected to the server. The server can't get data from both the server itself and the Proxy running on Debian 10. I also tried to open the ports 10050 on both the server and the proxy but this didn't help either. The zabbix agent configuration file is also configured to listen to port 10050 and is configured to send data to the server.

    I have solved this by configuring the Server and ServerActive to the IP of the Docker container. See this post: https://www.zabbix.com/forum/zabbix-...-zabbix-server
