# Duet Web Console (DWC)

## Rejected by the Duet

![](/files/-LHFAJ5ftIekg9k3aTcJ)

### Problem

When attempting to connect to the Promega the error "Your Duet rejected the HTTP request: page not found" is shown. 

This indicates that the web pages of the Duet web server can not be loaded from the SD card. Usually the problem lies in the SD card not being properly mounted to the system. This can happen if you ejected the SD card and then put it back into the Duet board while it was powered. 

### Solution

* Reboot the Duet Maestro board with the microSD card properly fitted inside.
* Reformat the microSD card.
* [Update the microSD card files.](broken://pages/-LH1ZbQK2pREbHCZ8zcK)
* [Update the Duet Web Firmware.](/documentation/software-firmware/updating-firmware.md)

### Solutions

* Ensure that your computer has a proper connection to the local network. It is possible that the Duet is not disconnected from the network but your computer is.
* Ensure that the Duet has a proper connection to your local network.
* [Try configuring a static IP address](broken://pages/-LOshvboTbWC-C0o-1ky#changing-the-network-settings-via-sd). It is possible that the router is continuously changing the IP address of your Promega.
* Go to *Settings > General* on the Duet Web Console and increase the *Status Update Interval* and *Maximum Number of AJAX Retries*.

## 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://promega.printm3d.com/how-to-troubleshoot/duet-web-console-dwc.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.
