Description

This is an issue that occurs when downloading any Twitch video. Apparently, they updated a certificate or changed the location of the m3u3 file. This download error happens with other Twitch downloader apps, but since it was not reported here yet, I figured I would let everyone know. Thanks for all the work on this program.
