# Mitigating Instrument Platform Services Errors on the MiSeq i100 Series

**Background**

The Control Software on the MiSeq i100 Series establishes a connection between the user-facing control computer and the internal compute engine that manages data processing. If this connection is not established successfully, the Control Software presents the following error:

![](/files/5fRno6FZe9YqbyfCxe1q)

There was a problem with instrument platform services. You can try to restart the control software, or shutdown and restart the instrument.

If this issue presents, select **Restart Application** to restart the Control Software and allow the Software to re-establish the connection between the two computers.

Do **NOT** select Shut down as this can frequently result in the issue persisting. If the issue persists after selecting **Restart Application**, contact [Illumina Tech Support](https://www.illumina.com/company/contact-us.html).

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## 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://knowledge.illumina.com/instrumentation/miseq-i100-series/instrumentation-miseq-i100-series-troubleshooting-list/000009545.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.
