[SOLVED] Prevent DNS leak with update-systemd-resolved not working

After I read this statement

However if you have systemd 229 or newer the better option is to use script from https://github.com/jonathanio/update-systemd-resolved which uses DBus calls instead of creating temporary *.network files.

here
I tried to prevent DNS leaking with the update-systemd-resolved script, but I don't get it to work.
My DNS is always leaking.

I installed updated-systemd-resolved via AUR,  the

systemd-resolved.service

is enabled
and I modified my

/etc/nsswitch.conf

with this line

# Don't use /etc/resolv.conf at all
hosts: files resolve myhostname

and added following lines to my openvpn client file

script-security 2
setenv PATH /usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin
up /etc/openvpn/update-systemd-resolved
down /etc/openvpn/update-systemd-resolved
down-pre

When I check the status of  systemd-resolved.service  after I started openvpn
I see

systemd-resolved[535]: Switching to DNS server XXX.XXX.XX.X for interface tun0.

  with XXX is the IP pushed from the openvpn server.

But when I do a DNS Leaktest, my DNS is always leaking!
Some help would be really appreciated!
