Pour supprimer ce type d’erreur :

[error] 2239#2239: *454376 access forbidden by rule, client: 127.0.0.1, server: 127.0.0.1, request: "GET /data/.ocdata?t=1591823240128 HTTP/1.1", host: "127.0.0.1"

J’ai modifié la configuration de NGINX.
Sur les fichiers /etc/nginx/conf.d/nextcloud-local.conf & /etc/nginx/conf.d/nextcloud.conf . J’ai ajouté :

    location = /data/htaccesstest.txt {
    allow all;
    log_not_found off;
    access_log off;
    }
    location = /data/\.ocdata {
    access_log off;
    }

Pour relancer :

systemctl restart nginx.service
