HTTP status error (thrown by HttpReader when the server answers with a status other than 2xx, except
416, which throws ERR_HTTP_RANGE instead)
Remarks
This message is a prefix: the status text, or the status code when the server sends none, is
appended to it, so it is matched with String#startsWith rather than with an equality test.
