Can't get it to run in privileged mode

I'm trying to get the Docker image to work but http://127.0.0.1:5666/ doesn't work, I'm guessing due to You need to execute this container in privileged mode at least once!. I'm passing the --privileged flag though.

What am I doing wrong?

C:\>docker run --privileged --name=Phlex --net=host digitalhigh/phlex
