What causes the 'janitor AI' error when using Argo Tunnel?

The 'janitor AI' error in Argo Tunnel usually indicates an issue with the `janitor` component, which is responsible for managing the tunnel's configuration and lifecycle. Common causes include misconfigurations in the `janitor` configuration, problems with the underlying kube-proxy, issues with the authentication credentials used by `janitor`, or conflicts with other components within the Kubernetes cluster. It also could indicate a problem during the initialization or upgrade process of the janitor component itself.
