Quick answer

If the Cursor agent fails, hangs on Planning next moves or never starts, the cause is usually network (HTTP/2), peak-hour load, a stalled extension host or a usage limit. Try Disable HTTP/2, a different model and an update.

Most likely fix: Retry with another model

Try these in order — the most common fix is first.

  1. 1. Retry with another model

    1. Wait a few minutes then retry
    2. Switch from the current model to Auto or an older model
