The server did not return an HTML page
Resolve the non_html_response scan error and understand when to start a new scan.

Why this happens
The server returned non-HTML content, such as Markdown, JSON, or a PDF. No accessibility audit was performed on that response.
What to do
- Ensure this URL serves its original HTML to the crawler, or use an HTML endpoint provided by the site owner. Converting Markdown to HTML cannot reproduce the website’s accessibility.
- Confirm that the target page and login method match the project you selected.
- After correcting the cause, start a new scan. Keep the original scan ID if you need support.
Before you retry
Repeating the same request without changing the cause may produce the same result. Never share credentials, session files, or sensitive screenshots in a support request.
