I'm having a very weird issue when connecting to an Ubuntu VM inside Proxmox through RDP. Let me describe the different scenarios:
1. If I connect from a Windows PC (physical computer) to the Ubuntu VM inside Proxmox, I often get an encryption error and my Windows machine gets disconnected. A good way to replicate the issue fast is to stream video content while connected on a RDP session.
2. If I connect from a virtual machine (Windows or Linux, doesn't matter) to the Ubuntu VM, I don't get the encryption error.
3. If I connect from a Windows PC (physical computer) to an Ubuntu installed on a virtualbox VM, I don't get the encryption error either.
In the following video, you can see a comparison of the 1st and the 3rd scenario. On the left, I'm connected to an Ubuntu vm inside proxmox and on the right I'm connected to a vm inside virtualbox.
I found a post in askubuntu that explains the same issue I'm having.
I don't know if this is a Proxmox issue, an Ubuntu issue or an RDP issue but I thought this might be a good place to share it.
BTW, on a different note, I've noticed that my graphical performance is a bit better when connecting with RDP to the virtualbox ubuntu vm than to the proxmox ubuntu vm. It's quite noticeable when moving windows around. Why is that? Shouldn't it be the other way around? I have allocated the same amount of resources to both vms (2 CPUs and 8 gigs of RAM.
