Error 502 when trying to download SoundCloud channel, but not track

[Fabian42]

#25303 was closed as "duplicate" without actually pointing to any other report, therefore making it a duplicate of nothing, and nobody replied to my question what it was supposed to be a duplicate of. So I guess I'll have to report this again. Maybe it was resolved by accident, but even then I don't know why Github even allows resolving a report as a duplicate of nothing. If it was intentionally resolved as duplicate, please tell me what it is supposed to duplicate.

Description

When trying to download everything from a SoundCloud channel either using the direct channel URL (like https://soundcloud.com/fabian-roeling) or specifically the "tracks" URL (like https://soundcloud.com/fabian-roeling/tracks), the 502 error seen above occurs and nothing is downloaded. Downloading any track separately works normally.
