Pourquoi l'agent ne remonte pas l'inventaire vers le serveur?

Bonjour dans le cas de mon stage je réalise une plateforme OCS/GLPI mais l'agent ne se connecte pas au serveur.

Voici les logs de l'agent:

==============================================================================

Est-ce que quelqu'un peut m'aider sur ce coup?

Merci d'avance.
