Solution: Use NFS -_-'

Hello. I've been using hotio's qbittorent, radarr and sonarr images for a while and I've been really happy with it. But A few weeks ago, I started having problems with radarr failing to copy my files to the destination folder. I have qbittorrent on machine A and my video server on machine B (called "orbiter"). I mounted destination folder on machine B to machine A like follow: sudo mount -t cifs //orbiter/Video/ /mnt/OrbiterVideo -o username=root,password=omgstrongpassword,uid=998,gid=100

And added it to fstab: //orbiter/Video /mnt/OrbiterVideo/ cifs username=root,password=omgstrongpassword,iocharset=utf8,noperm,uid=998,gid=100 0 0

Now, here are my docker-compose for qbittorrent and radarr :

QBittorrentVPN

version: "3.7"

services:
  qbittorrent:
    container_name: qbittorrentvpn
    image: cr.hotio.dev/hotio/qbittorrent
    ports:
      - 8992:8992
      - 8118:8118
    environment:

     # - VPN_ADDITIONAL_PORTS
      - VPN_IP_CHECK_DELAY=5
      - PRIVOXY_ENABLED=false
      - DEBUG=yes
    volumes:
      - /srv/path/Files/QBittorrentVPN:/config
      - /srv/path/Files/QBittorrentVPN/downloads:/downloads

    sysctls:
      - net.ipv4.conf.all.src_valid_mark=1
      - net.ipv6.conf.all.disable_ipv6=1
    restart: unless-stopped

Radarr

version: "3.7"

services:
  radarr:
    container_name: radarr
    hostname: Radarr
    image: cr.hotio.dev/hotio/radarr
    ports:
      - "7878:7878"
    environment:
      - PUID=998
      - PGID=100
      - UMASK=002
      - TZ=Europe/Paris
    volumes:
      - /srv/path/Files/Radarr/config:/config
      - /srv/path/Files/QBittorrentVPN/downloads:/downloads
      - /mnt/OrbiterVideo/movies/:/movies
    restart: unless-stopped

Radarr manages to grab and download a movie, but it fails to copy it:

It is important to note that I didn't change anything in my config.

Is there something I am doing wrong here ? I can't see through this anymore.
