I have Kubernetes v1.10.0 and minikube v0.28 installed in MacOS 10.13.5. But while starting the minikube, I am getting constant errors:

$ minikube start

Setting up certs...
Connecting to cluster...
Setting up kubeconfig...
Starting cluster components...
E0708 16:13:43.193267   13864 start.go:294] Error starting cluster:  timed out waiting to unmark master: getting node minikube: Get https://192.168.99.100:8443/api/v1/nodes/minikube: dial tcp 192.168.99.100:8443: i/o timeout

i have also tried $minikube start and $minikube delete as well as reinstallation of minikubes versions but that didn’t help.

$ minikube version
minikube version: v0.28.0

$ kubectl version
Client Version: version.Info{Major:"1", Minor:"11", GitVersion:"v1.11.0", GitCommit:"91e7b4fd31fcd3d5f436da26c980becec37ceefe", GitTreeState:"clean", BuildDate:"2018-06-27T20:17:28Z", GoVersion:"go1.10.2", Compiler:"gc", Platform:"darwin/amd64"}
Unable to connect to the server: dial tcp 192.168.99.100:8443: i/o timeout

Even I am not able to ping the virtual machine . But I can see the minikube VM in my virtualBox in Running status.
