Welcome Rose Jablonski,
Thank you for reaching out to Microsoft Q&A forum.
To help narrow this down, could you please confirm:
- Are you using Copilot on the web browser, the Copilot app, or Windows Copilot?
- Are you signed in with a personal Microsoft account (Outlook.com, Hotmail.com, Live.com)?
- Does the error appear for every prompt, or only certain requests?
In the meantime, please try these quick checks:
- Sign out of Copilot, then sign back in with your Microsoft account.
- Refresh the page or completely close and reopen the Copilot app.
- Try Copilot in an InPrivate/Incognito browser window.
- Test from a different network (for example, mobile hotspot) if available.
