VPN on Z10 doesn't work??

Hello there.

i'm trying to set up a vpn connection on my bb z10. but it just dont work!
i tried vpnreactor and cisco client and some others, i followed the instructions and everything a couple of times, i even went to ict at my work and he got a nexus6, and tried to make a connection with my user name at vpnreactor but nope still don't work?

the times when i tried i got the message dns problem or couldnt send the package or time out.

is there someone else who got the same problem??
or has this something to do with the latest update from blackberry?

can somebody help me out with this?

thnx in advance. Tom
