If your hypothesis is correct, then the old credentials would work (because they are cached) and the job would print, just like when the credentials are correct. yes?

However, since it is not printing, that means the credentials are NOT being checked before the 200 is sent but they are being checked (correctly) _later_ so the next request by the client gives out the 401 error.
