vnc console change certificate

Hi all,

Has someone been able to change the default certificate on proxmox and at the same time have the vnc console working?
Getting apache to work is easy but no matter what I do I cannot make the vnc console working with another certificate than the one provide by default from the proxmox installation.

The error message from Java:
