## Debugging
### unable to cache ISO... connection refused
```
Unable to start VM: unable to cache ISO: https://storage.googleapis.com/minikube/iso/minikube.iso:
failed to download: failed to download to temp file: download failed: 5 error(s) occurred:
* Temporary download error: Get https://storage.googleapis.com/minikube/iso/minikube.iso:
proxyconnect tcp: dial tcp <host>:<port>: connect: connection refused
```
This error indicates that the host:port combination defined by HTTPS_PROXY is incorrect, or that the proxy is unavailable.
## Unable to pull images..Client.Timeout exceeded while awaiting headers
```
Unable to pull images, which may be OK:
failed to pull image "k8s.gcr.io/kube-apiserver:v1.13.3": output: Error response from daemon:
Get https://k8s.gcr.io/v2/: net/http: request canceled while waiting for connection
(Client.Timeout exceeded while awaiting headers)
```
This error indicates that the container runtime running within the VM does not have access to the internet. Verify that you are passing the appropriate value to `--docker-env HTTPS_PROXY`.
