NO VNC console Disconnect 1006 NEW

as i already said, i do not really know why this is happening for you, but the lack of responses from others indicates that it is something unique to your environment
so if you can i would try to connect to another pve on maybe another network/computer and maybe also try 5.0 and see if any of this makes a difference
 
Sorry for picking up this „older“ post.

@dcsapak I habe the exakt Same problem on proxmox 5.3 ... any ideas how to fix this bug?
