    Zabbix agent - "assuming agent dropped connection because access permissions"

    Hi,

    So I have a small enterprise zabbix for basic monitoring, and somehow I can't seem to get the agents to work. I always end up getting that ZBX status red with the message "assuming agent dropped connection because access permissions".

    I've already checked the ports 10050 and 10051 on both sides, telnet both sides, tried a million agent.conf configs but I can't seem to solve it.

    Zabbix_agentd,conf:
    Server=192.168.46.137
    Server_Active=192.168.46.137

    I have the hostname of the machine i want to monitor configured the same as in the browser hostname setting.
    The only host that works is the Zabbix server itself. Every other host displays the message above.

    Hi!
    I have discovered the same problem today. Agents were upgraded to 4.0.1 but server is still 3.4.4. Exactly the same error message.

      I had the issue on CENTOS 7 due to SELinux. Set it to permissive using setenforce to see if that resolves you issue maybe?

        hey guys, I have sellinux off since the beggining.

        Fortunately I fixed it by upgrading to zabbix 4.0, what a coincidence they release an update right when I have the problem :P

        Thanks anyway
