Describe the bug

Failed to create ip link wg0

To Reproduce using docker-compose

Install Docker WSL2 on Windows 11.

docker-compose.yml if used (hide credentials)

version: '3.8'
services:
  nordlynx:
    image: ghcr.io/bubuntux/nordlynx
    cap_add:
      - NET_ADMIN #required
      - SYS_MODULE
    environment:
      - PRIVATE_KEY=XXX #required
    sysctls:
      - net.ipv6.conf.all.disable_ipv6=1

Expected behavior

Running curl checkip.amazonaws.com inside the container should return the VPN IP but freeze instead.
