# Instance(s) Fail to Delete When Host is Down/Offline

## Problem

* Instances(s) fail to delete.
* The hypervisor associated with the affected instance(s) is offline.
* “Unexpected API Error” message appears when attempting to delete the instance.

## Environment

* Platform9 Managed OpenStack - v3.6.0 and Higher

## Cause

* Either the hypervisor is down or removed.
* The ***nova-compute*** service on the host is stopped.
* Connectivity issues are present between the hypervisor and the Management Plane.

## Resolution

1. Identify the **UUID** of the host on which each instance resides.

{% tabs %}
{% tab title="None" %}

```none
# openstack server show -c OS-EXT-SRV-ATTR:host [INSTANCE_UUID]
```

{% endtab %}
{% endtabs %}

2. Force the compute service for the host to report as down.

{% tabs %}
{% tab title="None" %}

```none
# nova service-force-down [HOST_UUID]
```

{% endtab %}
{% endtabs %}

3. Delete the instance.

{% tabs %}
{% tab title="None" %}

```none
# openstack server delete [INSTANCE_UUID]
```

{% endtab %}
{% endtabs %}
