Problem with vnc viewe in Proxmox 2

I would like to thank everyone who made ​​it possible Proxmox 2.


I have been testing proxmox and all is correct, but I have a doubt, is the next:


We have a vnc viewer in our site for connect with our vps. In Proxmox 1.9 all is correct but in Proxmox 2 not works.


The template use for test is Debian-5.0.


If I push the botton "console" from proxmox interface is ok:

root 78590 0.0 0.0 2764 1484 /var/lib/vz/root/105/dev/pts/0 Ss+ 10:00 0:00 -bash


But if I want execute my vnc viewer manually not works. The error is:


Error: Server did not offer supported security type


Thanks.
