Interrupted downloads should attempt to resume instead of instantly stopping

It appears that if a download is suddenly interrupted, potentially from an ISP interfering. It usually appears this would throw the following error as soon as it happens.

A bit of chatting with pjb suggested this may be because the download somehow gets interrupted suddenly.

Chatting with the user they reported the download screen was present for a bit before erroring out. Which may be the culprit.
