VPN funktioniert nicht

[LV426]

Moin!
Ich kann mich von meinem Notebook nicht am OpenVPN Server (aktuelles DSM, DS 213j) anmelden.

Config auf dem Client:

dev tun
tls-client

remote YYYYYY.goip.de 1194

#float
redirect-gateway def1
pull
proto udp
script-security 2
remote-cert-tls server
comp-lzo
reneg-sec 0
cipher AES-256-CBC
auth SHA512
auth-user-pass
<ca>YYYYYYYYYYYYYYYYYYYY</ca>

Log auf dem client:
