New install - Bepinex mods not loading

[dcgsteve]

Hiya - was playing fine but now moved to new server so re-installing from scratch, i.e. clean config & data directories

docker-compose.yml:

version: "3"

services:
  valheim:
    image: ghcr.io/lloesche/valheim-server
    container_name: valheim1
    cap_add:
      - sys_nice
    volumes:
      - /mnt/nas1/cluster/data/valheim/config:/config
      - /mnt/nas1/cluster/data/valheim/data:/opt/valheim
    ports:
      - "2456-2457:2456-2457/udp"
      - "8011:9001/tcp"
    restart: unless-stopped
    stop_grace_period: 2m
    env_file:
      - ./valheim.env

valheim.env:

BEPINEX=true

BepInEx is triggered:

Mods are synced to directory ok:

Dec 23 13:47:22 supervisord: valheim-updater INFO - Syncing BepInEx plugins from /config/bepinex/plugins/ -> /opt/valheim/bepinex.tmp/BepInEx/plugins

Dec 23 13:47:22 supervisord: valheim-updater >f+++++++++ AnyPortal.dll
Dec 23 13:47:22 supervisord: valheim-updater >f+++++++++ Jotunn.dll

BepInEx seemed to be installed ok:

Dec 23 13:47:22 supervisord: valheim-updater DEBUG - [166] - Successfully installed BepInEx mod

But Jotunn.dll and AnyPortal.dll are not loaded :(

The sync has worked ok (I've bash'd inside the container and they are sitting in both directories)

Any ideas what's happened here and why they don't load?

i also cant get mods working in a dedicated linux server BUT it works in windows. the log says bepinex is loaded but no plugins.
