+## Troubleshooting Helm Install Errors
+
+If you encounter the following error while running `helm install`:

+
+This error can occur when network proxies or VPN clients like **Z-Scaler** interfere with Helm’s communication with the Kubernetes API server. In some cases, even if Z-Scaler appears to be disabled, it may still be running in the background.

+
+- Ensure Z-Scaler is fully **terminated or logged out**, not just disabled.
+- Retry the `helm install` command after confirming your network is not filtered through such a service.
+- This issue and its resolution were discussed in [GitHub issue #30860](https://github.com/helm/helm/issues/30860).
