Failed to open/create the internal network

Started playing with Docker today using the docker toolbox running on Win 8.1. I tried to run the hello-world test in the docker quickstart terminal, I got this error:

$ docker run hello-world
Post http://127.0.0.1:2375/v1.20/containers/create: dial tcp 127.0.0.1:2375: ConnectEx tcp: No connection could be made because the target machine actively refused it…

  • *Are you trying to connect to a TLS-enabled daemon without TLS?
  • *Is your docker daemon up and running?

This led to to check the docker daemon in the vm created by default in virtualbox. The vm failed to start with the error:

Failed to open a session for the virtual machine default.
Failed to open/create the internal network ‘HostInterfaceNetworking-VirtualBox Host-Only Ethernet Adapter #2’ (VERR_INTNET_FLT_IF_NOT_FOUND).
Failed to attach the network LUN (VERR_INTNET_FLT_IF_NOT_FOUND).
Result Code: E_FAIL (0x80004005)
Component: ConsoleWrap
Interface: IConsole {872da645-4a9b-1727-bee2-5585105b9eed}

Any idea what’s causing the problem? Your help is much appreciated.

I had a similar problem on Windows 10. I am new to Docker:

Can it run with sudo?

Make sure the vm in virtual box is ok.reboot if needed
