OCS access to /download/ forbidden

Bonjour à tous.

Depuis un certain temps j'ai des problèmes d'accès à mon répertoire download sur mon serveur OCS.

Version OCS : 2.4 et Apache/2.4.25 (Debian) et Debian : 9.3

Je vous donne mes fichiers de configuration ocs :

En plus tester l'accessibilité du répertoire download j'y ai crée un petit fichier test.html dont root est propriétaireh

https://ip_ocs/download/test.html ou http://ip_ocs/download/test.html Accès OK

https://ip_ocs/download/1519651014/ ou http://ip_ocs/download/1519651014/ Accès forbidden
