# Fix a page Darwin couldn't read

Knowledge → Needs attention: what Couldn’t read, Refresh failed and Reading mean, why a page fails, how Darwin retries, and how to fix the page or put its facts somewhere your agent can read them.

This is the Markdown version of https://www.meetdarwin.ai/help/knowledge/fix-a-page-darwin-couldnt-read, published by Darwin and generated on 27 October 2026.

Find it in Darwin: Knowledge → Needs attention (https://app.meetdarwin.ai/admin/agent?tab=knowledge). Updated Oct 26, 2026.

A page Darwin can't read gives your agent nothing to answer from, or an old copy. **Needs attention** collects those pages in one place.

1. **Open Needs attention**

   Select **Knowledge** in the sidebar, open the view menu at the top left (1) and choose **Needs attention**. It lists pages that are **Reading**, **Refresh failed** or **Couldn’t read** (2).

2. **See what went wrong**

   Point at the status to see Darwin's reason. **Reporting → Knowledge** also lists **Failing pages** with **What went wrong** and when Darwin last tried.

   - **Couldn’t read**: Darwin has never read the page, so your agent has nothing from it.
   - **Refresh failed**: the latest read failed. Your agent keeps answering from the copy it read before.
   - **Reading**: Darwin is reading it now. Wait a few minutes.

3. **Fix the cause**

   Most failures come from the page itself:

   - It no longer exists, or moved. Untick **Use** and add the new address under **Add knowledge → Pages one by one**.
   - It's behind a login, or shows its text only after a click. Upload the content as a document, or add the facts to your [business context](https://www.meetdarwin.ai/help/knowledge/business-context).
   - Your site was down or blocked Darwin for a moment. Select **Refresh** to try again.

4. **Refresh, then save**

   After you fix the page, select **Refresh** beside it. When it reads **Learned**, select **Save changes** if you changed anything else on Knowledge.

## Good to know

- Darwin retries a page it has never read by itself: after 1 hour, then 2, 4, 8 and 16 hours. After that it stops trying until you select **Refresh**.
- A page that fails doesn't stop the others from being read.
- If many pages fail at once, check that your website is up, then [contact support](https://www.meetdarwin.ai/help/support/contact-support) with one of the addresses.

- [Keep pages up to date](https://www.meetdarwin.ai/help/knowledge/keep-pages-up-to-date): Refresh, Re-fetch and Auto-refresh.
- [Write your business context](https://www.meetdarwin.ai/help/knowledge/business-context): Facts your pages can’t give your agent.
