Disconnect reason: E: TCP: SECURITY_ERROR Error #2048

[Thomas De Maerschalck]

Hello

I recently started using phpvirtualbox.
It first it all worked well, but now my guest OS throws this error.
Problem:

When i use console or RDP, it will give me an error, on console (website) it will give me the "Disconnect reason: E: TCP: SECURITY_ERROR Error #2048" message.

It used to work. Now it doesn't. I even used an older snapshot. Same error!
The server does still work. I can login with ssh. But I installed desktop on the server, slimmed down unity desktop that was slow as hell, was going to change to something else. 3D accelerations down work for ubuntu, but do for the windows guests.

Just so you know, I'm a student, programming. All my knowledge is self learned and very basic.

Host:
Ubuntu server 14.04
VirtualBox 5.0.14
phpVirtualBox 5.0-5 -/- VirtualBox 5.0.x compatible

Guest:
Ubuntu server 14.04 with slimmed down unity desktop (rdp from webpage throws error)
Guest drives installed

Windows server 2012 (rdp from webpage works)
guest drives installed

I'm installing a new Ubuntu machine right now, it works, like the windows VMs, so it should be a problem with the VM, if some one knows what, do tell me.

Recreating the server will take some time...
