docker: Error response from daemon: invalid cluster node while attaching to network

Question

I am newbe on docker and I have this problem:

On an image that runs fine (to an extent), I try to run (from the same image) adding --network and I get this error:

    PS C:\MyApp> docker run -v C:\MyApp:C:\MyApp --network=host -dit myApp_des

docker: Error response from daemon: invalid cluster node while attaching to network.

No VPN active. I thought it was somthing easy. Same results on --net=bridge. On --network=none it works fine.

Thanks in advance.
