Error opening configuration file: openvpn closes connection and kills container

[wattsra]

Whenever I start this container it immediately fails and kills itself with the error below.

Options error: In [CMD-LINE]:1: Error opening configuration file: /config/openvpn/id-jak.prod.surfshark.comsurfshark_openvpn_tcp.ovpn

I am running on portainer with the attached yml file as a stack. I believe that this should sort out the "privleged" requirement.

I suspect that it is linked to this issue, but the solutions/workarounds posted there don't seem to work for me : https://github.com/haugene/docker-transmission-openvpn/issues/1839

yaml file:

version: '3.3'
services:
  jackettvpn:
    image: dyonr/jackettvpn:latest
    privileged: true
    restart: unless-stopped
    cap_add:
      - NET_ADMIN
    ports:
      - 9117:9117 # http://nas-ip:9091 to access ui
    environment:
      - VPN_ENABLED=yes
      - VPN_TYPE=openvpn
      - LAN_NETWORK=192.168.50.0/24
    volumes:
      - /volume1/docker/jackettvpn:/config # change to download dir
    network_mode: bridge

It does indeed seem related to the issue you shared.
Did you try this yet?
Unchecking "execute container using high privilege" and re-checking it again fixes the issue with DSM 7.0 after migration.

And, did you also try other solutions of that issue, like this one?

I found the fix and already posted it in the mentioned qbittorrentvpn issue, but I thought I'd put it here also.

Add the following lines to your compose file:

  devices:
    - /dev/net/tun

Please refer to this issue for a solution, as @SheepKid12 also mentioned:

I have the same problem even after trying the solution from the other posts...

Same. My yaml is identical to yours and I get the same read error about the openvpn config file.

Made sure to add the cap_add: - NET_ADMIN and privileged parameters.

Interestingly it worked for my transmission docker instance but not jackett.

Running on Synology DSM 7
