If you are using the Mac or Windows CLI to enter a Docker based studio (`hab studio enter`), you may see

```auto
error pulling image configuration: received unexpected HTTP status: 500 Internal Server Error
✗✗✗
✗✗✗ The Docker image habitat-docker-registry.bintray.io/studio:0.18.0 is unreachable due to a network error.
✗✗✗ The image must be reachable to ensure the versions of hab inside and outside the studio match.
✗✗✗ You can specify your own Docker image using the HAB_DOCKER_STUDIO_IMAGE environment variable.

```

This can be cleared up by manually removing previous habitat studio images from your local cache of Docker images.

Example:

```auto
docker rmi .habitat-docker-registry.bintray.io/studio:latest --force

```
