Description

After upgrading from 1.0.0 (docker) to 1.1.0 (docker), the guacamole cannot connect to virtual box VMs with virtualbox RDP.

Below is the error logs I got while trying to connect to a virtual box client through VRDP.

On the contrary, there is no problem for guacamole to connect to a machine with the windows built-in RDP.
