Mullvad OpenVPN Configs not working

[DEAD1SIDE]

I tried to run the vpn with the Mullvad configs but it always tells me :

/sbin/ip -6 addr add -ipv6-/64 dev tun0
RTNETLINK answers: Permission denied
Linux ip -6 addr add failed: external program exited with error status: 2
Exiting due to fatal error

Anyone got an Idea what to do?

Add this to your docker-compose vpn container configuration:

services:
  vpn:
    ...
    sysctls:
      - "net.ipv6.conf.all.disable_ipv6=0"
    ..

This worked for me
