Description

I'm not able to download any Twitch VODs. This is a recent bug as I'm not able to download a VOD I downloaded just yesterday.

Rebooting solved this.

I'm getting the same error when trying to download twitch VODs:

This happens on 2 different machines, one Debian (testing) and one Mac OS X 10.14.5 (installed from homebrew, version given is 2019.06.27).

Since it doesn't seem to be universally broken, what could be causing my 2 machines to fail? They are both on my home network—could it be something like DNS?

How do I find the actual URL that is giving the 404?

I'm getting the same error with version 2019.07.02, on Windows 10 and macOS Mojave. I have so far tried two different wifi networks, with the same results. All VODs I have tested work fine on my computers' browsers. My Windows log is:

I started having this issue about a week ago, but it went away. It came back sometime between June 28 and now (July 1). The URL in the log is one that I had already downloaded before, but it stopped working along with every other VOD I try.

(Should I make a new issue for this? It's the exact same problem as the original post... I don't know GitHub etiquette)
