I have been following this to the letter (and have redone the steps a number of times) without any luck. http://wiki.mikrotik.com/wiki/OpenVPN_C ... ep_by_Step

I can complete this tutorial, and get it to connect via an OpenVPN connection on the router, but when I try to get it working via OpenVPN Gui in Windows I cannot get it going.

I am testing this internally, but the OpenVPN server is on a different subnet.

The error I am getting is:

I have a GoDaddy Certificate installed on the Mikrotik box and it has had the key imported as well and is displaying.

My OpenVPN config is:
client
dev tap
proto tcp
remote vpn.****.co.nz 1194
resolv-retry infinite
nobind
persist-key
persist-tun
ca AC.crt
cipher AES-256-CBC
auth MD5
auth-user-pass
auth-nocache
register-dns
redirect-gateway def1

The certificate is in the same folder as the config file (I have done it like this on other OpenVPN installs and it works fine).

I have tried googling the errors and cannot find a definitive answer, I have tried recreating the certificates multiple times.
I am running RouterOS 6.3 ( I have tried 6.4 & 6.5 also)


Any help would be greatly appreciated.
