ERROR: Cannot ioctl TUNSETIFF tun: Operation not permitted (errno=1)

[zyssai]

Hi, I'm coming from deprecated <guillaumedsde/qbittorrent-openvpn:latest>
Everything worked fine, but now i'm unable to get <guillaumedsde/alpine-qbittorrent-openvpn:latest> working
I followed #63, without success.

All my containers are under traefik v2.
VPN is custom from VPNUnlimited.

2022-03-30 13:46:54 DEPRECATED OPTION: --cipher set to 'AES-256-CBC' but missing in --data-ciphers (AES-256-GCM:AES-128-GCM). Future OpenVPN version will ignore --cipher for cipher negotiations. Add 'AES-256-CBC' to --data-ciphers or change --cipher 'AES-256-CBC' to --data-ciphers-fallback 'AES-256-CBC' to silence this warning.
