# Unable to access the PMK UI due to sunpike-kine issues

## Problem

* PMK UI is failing and getting stuck on L`oading region data.`
* Not able to access the PMK clusters and hosts through UI.

## Environment

* Platform9 Managed Kubernetes - All Versions

## Cause

* The connection to MySQL (RDS) gets blocked due to connection errors observed by the Sunpike Kine service.
* This is observed when there are frequent errors observed when clients try to connect to MySQL.

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

```ruby
time="[Timestamp]" level=fatal msg="building kine: Error 1129: Host '[IP]' is blocked because of many connection errors; unblock with 'mysqladmin flush-hosts'"
```

{% endtab %}
{% endtabs %}

## Resolution

* Manually execute `_**mysqladmin flush-hosts`\*\*\_ command to unblock the connection from Sunpike to MySQL.
* This is a known issue and is being tracked via JIRA internally.

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

Perform an HTTP GET request on the following URL with the `ask` and `goal` query parameters:

```
GET https://platform9.com/kb/pmk/solutions/unable-to-access-the-pmk-ui-due-to-sunpike-kine-issues.md?ask=<question>&goal=<user_goal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is what the user is ultimately trying to achieve, the reason they need the answer. Sharing it helps GitBook give you a better, more relevant answer. A goal is most helpful when it describes the outcome the user wants rather than restating the question. For example, with `ask=how do I create an API token`, a goal like `automate deployments from our CI pipeline` lets GitBook tailor the answer to that use case.

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.
