OpenVPN Connection problems

Hi all,
i have just set up a new router for our customer and I am unable to connect to OpenVPN server on routerboard - I get “Connection reset”

My setup:

RB2011iL-RM w/ RouterOS 6.7

OpenVPN profile settings:

 name="openvpn" local-address=10.10.10.10 remote-address=OPENVPN_POOL 
 use-mpls=default use-compression=default use-vj-compression=default 
 use-encryption=default only-one=default change-tcp-mss=default 
 address-list="" dns-server=192.168.0.240

OpenVPN server settings:

                     
enabled: yes
port: 65534
mode: ip
netmask: 24
mac-address: FE:C7:52:61:47:19
max-mtu: 1500
keepalive-timeout: disabled
default-profile: openvpn
certificate: cert_21
require-client-certificate: yes
auth: sha1,md5
cipher: blowfish128,aes128,aes192,aes256

OpenVPN Client (Windows 7) config file:

dev tun

ca ca.crt 
cert client.crt
key client.key
tls-client
port 65534

auth SHA1

route 192.168.0.0 255.255.255.0 10.10.10.10

and finally OpenVPN logfile:

This: “Tue Jan 20 16:23:37 2015 us=727581 Connection reset, restarting [0]” is what bothers me, because I am unable to make this work and already have spent a few hours trying different possibilites… Can someone help me please?
Thank you in advance.

what do you get on the routerboard log (with ovpn debug option in the logging options)?

Nothing more, than “TCP Connection established from 123.123.123.123”
It seems to me like nothing is working…

      debug

I have identical problem.
Somebody have any idea what to do?
