# Connection Issues Fix

## Connection Issues Fix

If your Xbox® controller does not connect through the Cronus Zen™, a full power cycle with the controller still attached resolves most cases.

{% hint style="warning" %}
Keep the Xbox® controller connected to the Zen throughout. You only ever disconnect and reconnect the **USB cables**, never the controller itself.
{% endhint %}

{% stepper %}
{% step %}

#### Disconnect the cables

With the controller still plugged in, remove both USB cables from the Zen:

* the cable in the **top port** (CONSOLE/PC)
* the cable in the **right port** (PROG)

Wait a few seconds so the Zen powers off fully.
{% endstep %}

{% step %}

#### Reconnect the cables

Plug both cables back into the same ports. The Zen powers on and detects the Xbox® controller.

In most cases everything works at this point.
{% endstep %}

{% step %}

#### If the controller does not respond

Press and hold the Xbox® **Guide** button on the controller to turn it on. It should now connect through the Zen.
{% endstep %}

{% step %}

#### If the problem persists

Perform a [Hard reset](/frequently-asked-questions/troubleshooting.md) on the Cronus Zen™, then repeat steps 1 to 3.
{% endstep %}
{% endstepper %}

## 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://guide.cronuszen.com/supported-devices/xboxseriesxs/connection-issues-fix.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.
