# Consul Service Cannot Start: "bind\_addr cannot be empty

## Problem

* A host is failing to converge on the ***pf9-ha-slave*** role.
* The following warnings are present in */var/log/pf9/pf9-ha.log.*

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

```none
ha-manager WARNING Consul service stopped. Retrying... ha-manager WARNING sudo service pf9-consul status returned non-zero code
```

{% endtab %}
{% endtabs %}

* In */var/log/pf9/pf9-consul.log*, the following error may also be observed.

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

```none
==> bind_addr cannot be empty
```

{% endtab %}
{% endtabs %}

## Environment

* Platform9 Managed OpenStack - All Versions
* AZ with High Availability Enabled

## Cause

The ***Cluster IP*** field which corresponds to the ***bind\_addr*** for Consul is empty for the corresponding host in Clarity UI.

## Resolution

1. Set the ***Cluster IP*** to an IP which is accessible by other hosts which are part of the same host aggregate, associated with the AZ for which High Availability is enabled.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://platform9.com/kb/pmo/solution/consul-service-cannot-start-bind_addr-cannot-be-empty.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
