takeRefusal

A server's refusal of an address this reader, or one it opened, had been reading, once, or null, the default (#453). A signed address that expired gets one: the server answers 401 or 403 to the next segment, the next playlist reload or the next range of the file, after the item had opened. The engine asks on its own passes and opens the item again through its resolver or its io factory, which hand out a fresh address, at the position it reached.

Report a refusal of the item's first open as a failure of that open instead, as always.
