Erreur 500 sur scan SNMP

Bonjour,
Je suis en train d'installer un serveur OCS et je rencontre une difficulté avec la fonctionnalité de scan snmp de l'agent linux, erreur 500 (détails dans les extraits de logs plus bas)
J'ai vérifier l'ensemble des fichiers de conf pour les liens et connexion a la bdd sans trouver d'erreurs

mon infra est composée de :
1 serveur pour la base de données

     OS : Debian 10.9

     mariadb : 10.3

1 serveur web (glpi/ocs) + agent ocs unix

     OS : Debian 10.11

     version ocs-server : OCSNG_UNIX_SERVER-2.9.1

     version OCS-agent : Ocsinventory-Unix-Agent-2.8.1

Hi,

the error "Cannot establish communication : 500 Internal Server Error" should not be a snmp error but a webserver error. Probably the server can't write on db. You can check z-ocsinventory-server.conf in webserver configuration.

Bye
