That's not what I'm asking (see previous posts). The system hostname is ignored by zabbix and you can set it to whatever you want.
What is essential is that the Hostname defined in zabbix_agentd.conf and the hostname defined in zabbix (UI, DB) when creating the host match.
And judging from the screenshot, your host is named "SANDBOX_2" in zabbix and not "SANDBOX2".
Rename host to "SANDBOX2" in zabbix UI and it should be fine.
Then you can restart zabbix_agentd so that you won't have to wait ~2 minutes before it tries again pulling active checks from zabbix_server.
