Cursor Agent Not Working
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
