Unknow error when request for a binary stream?

[mike442144]

I have two issues

1. The error information is unclear to judge what happened under the surface
2. In this case should not have had error because the same request works well in crawler-v1 or request.js

Because of the privacy issue I cannot paste the url, the only difference is downloading a .mp4 video stream. So myabe I use the W3School material for example https://media.w3.org/2010/05/sintel/trailer.mp4.

Could you do some test and fix both two of them? Thanks.
