Today, I came across with weird openvpn bug. I have seen before but forgot documentating that time. So here we go hopefully I remember this(more likely I won’t so) so writing this post…

After digging a bit, also reported here: https://0xacab.org/leap/bitmask-vpn/-/issues/457

You need add the following line in ovpn.conf file to allow list to fail gracefully:

pull-filter ignore "ifconfig-ipv6"
pull-filter ignore "route-ipv6"

then restart service should help.
