Problem host auto registration after agent 2 installed

[milkaZ]

Hello,

zabbix server is a fresh installation
zabbix_agent2 v6.4.12 has been installed and configured like this :

dpkg -i zabbix-agent2_6.4.12-1+debian12_amd64.deb

Server=192.168.21.236
ListenPort=10050
ServerActive=192.168.21.236
#Hostname=
HostnameItem=system.hostname
HostMetadataItem=system.uname
Timeout=30
Include=./zabbix_agent2.d/plugins.d/*.conf

systemctl start zabbix-agent2.service

On frontend 6.4,

	Linux_server	Métadonnées de l'hôte contient linux	Ajouter hôte Ajouter aux groupes d'hôtes: Discovered hosts, Linux servers Lier aux modèles: Linux by Zabbix agent	Activé
	Windows_server	Métadonnées de l'hôte contient windows	Ajouter hôte Ajouter aux groupes d'hôtes: Discovered hosts, Windows servers Lier aux modèles: Windows by Zabbix agent	Activé

	Auto discovery. Linux servers.	Valeur reçue contient Linux État de la découverte égal Fonctionne Type de service égal agent Zabbix	Ajouter aux groupes d'hôtes: Linux servers Lier aux modèles: Linux by Zabbix agent	Activé

My problem is that myhostname does not appear

If i manually add host, like this, it works well

hostname : myhostname
modeles : linux by zabbix agent
groupe d'hotes : linux serveurs
interfaces : Agent / 192.168.160.126 / myhostname / IP / 10050
proxy : none
activé : yes

Could you help me please to auto register host when agent is started on it ?

Thanks in advance.
