Wildcard SSL-VNC TLS handshake issue

[wahmed]

I recently installed wildcard SSL from Comodo in a Proxmox cluster and now VNC does not work any more. No matter which node i am trying to access it gives me the following error message:

Error: TLS handshake failed javax.net.ssl.SSLHandshakeException: Remote host closed connection during handshake

SSL is installed exactly as suggested in Proxmox wiki and verified that it is working properly. All nodes also have been rebooted just in case instead of just restarting services.
Any idea?

It is on Proxmox 3.3.

On the client(s) from which you use vnc you need to delete the cached vnc client (use the Java console) so that you get a fresh vnc client from your proxmox node.

No go. Cleared both Firefox and Chrome cache including Java cache. But getting the same handshake error. I turned on the console viewer and below is the data:

There no firewall in between. Trying to open the VNC console from local node.
