{% tabs %}
{% tab title="Javascript" %}

```javascript

Also, the clusteraddon associated with the kubernetes dashboard will be in installAddonError state:

{% tabs %}
{% tab title="Kubernetes Dashboard" %}

```javascript

```

{% endtab %}
{% endtabs %}

Environment

* Platform9 Managed Kubernetes - v5.5 and Higher

## Cause

The kubernetes dashboard pod is in crashLoopBackOff state due to the missing /etc/cni/net.d/calico-kubeconfig file in the node.

## Resolution

Restart PMK stack on the affected node, this should re-populate the file /etc/cni/net.d/calico-kubeconfig, and recreate the pods and related resources.

The commands shared below will restart PMK stack in the affected node:

{% tabs %}
{% tab title="Nodeletd Phases restart" %}

```javascript
sudo systemctl stop pf9-hostagent pf9-nodeletd 
sudo /opt/pf9/nodelet/nodeletd phases stop
sudo /opt/pf9/nodelet/nodeletd phases start
sudo systemctl start pf9-hostagent pf9-nodeletd
```

{% endtab %}
{% endtabs %}
