**To Reproduce**
Steps to reproduce the behavior:

**Expected behavior**
A clear and concise description of what you expected to happen.

**Environment**
* Kubernetes version:
* Distribution or cloud vendor (OpenShift, EKS, GKE, AKS, etc.):
* Other configuration options or runtime services (istio, etc.):
* vault-helm version:

Chart values:

```yaml
failed to fetch Helm repository index: failed to cache index to temporary file: failed to fetch https://helm.releases.hashicorp.com/index.yaml : 403 Forbidden

```

**Additional context**
Add any other context about the problem here.

Start by investigating the 403 response when fetching https://helm.releases.hashicorp.com/index.yaml and reviewing the reported IP address and RIPE information. The issue provides no chart version, Kubernetes environment, logs, or repository files; done would require determining whether access can be changed and confirming that Helm can fetch the repository index.
