Docker Machine Virtual Box Driver - Plugin dial tcp 127.0.0.1:51260: connectex

Hi,

Hope someone can help on this one…

Installed Docker Toolbox 18.02.0-ce on a Window 8.1 machine… but currently not able to create a new Docker Machine daemon on Virtual Box (v5.1.20)…

The error is always the same (I change the create line so that it will run in debug):

Docker Machine Version: 0.13.0, build 9ba6da9
Found binary path at D:\Utilities\Containers\Docker Toolbox\docker-machine.exe
Launching plugin server for driver virtualbox
Plugin server listening at address 127.0.0.1:51260
dial tcp 127.0.0.1:51260: connectex: A connection attempt failed because the con
nected party did not properly respond after a period of time or established conn
ection failed because connected host has failed to respond.
Looks like something went wrong… Press any key to continue…
Fdocker_engine/v1.36/version: open //./pipe/docker_engine: The system cannot find the file specified. In the default daemon

Has anyone already seen this issue?

Thanks
