Hello,
I worked with the Proxmox 1.8 Installation for one week. Everything worked fine. It's a Cluster with only Master and no other Node integrated.
Today, when I opened the VNC console in the Browser, the VNC console only shows half black and half white. In the syslog of the proxmox browser there is an error: vm 114 vnc proxy failed -256

A Reboot of the server doesn't help. The error occurs for every vm.

The virtual machine is running as a qm list shows. When I open a SSH shell on my Server and start the VNC in this shell (nc -l -p 5900 -c "qm vncproxy 114 1234") I can connect to the virtual machine via an external VNC viewer.

Any Idea?

post the output of 'pveversion -v' and tell details about your desktop browser and the used java plugin.
 
Hi,
today I tried again and everything worked normal. Maybe high network load was responsible for the error. I distributed an image per UDP over our network, when the error occured.

Thanks,
