Не подключается к zabbix серверу 4.4.6 zabbix агент 4.4.6 на rhel 7.6

Кто на ком стоял? (С)

Зачем агенту подключаться к серверу, кроме как за активными проверками? Где, когда и в результате чего возникает такая ошибка?

Что в конфиге агента?

Согласен, некорректно написал. Не опрашивается zabbix сервером zabbix agent. Ошибка возникает, если создать на сервере узел сети на котором находится zabbix-agent для того чтобы собирать по нему метрики. Конфиг агента:

#	Different Alias keys may reference the same item key.
#	For example, to retrieve the ID of user 'zabbix':
#	Alias=zabbix.userid:vfs.file.regexp[/etc/passwd,^zabbix:.:([0-9]+),,,,\1]
#	Now shorthand key zabbix.userid may be used to retrieve data.
#	Aliases can be used in HostMetadataItem but not in HostnameItem parameters.

Судя по

«zabbix_get -s 10.200.2.116 -k agent.ping» возвращает «1»

всё должно работать. Как на сервере настроен узел с агентом, какие указаны интерфейсы, порты? Можно прямо картинкой из веб-админки.
