Q: "Can’t download episodes from your feed." error when attempting to upload podcast from soundcloud

You've fallen over an oddity that Soundcloud keeps doing to people (or which people keep doing to Soundcloud), I have no idea why. The URL of your media file is

https://soundcloud.com/fantazyfoodtru/http://feeds.soundcloud.com/stream/2520573 21-fantazyfoodtruk-podcast-ep-1-s-1.mp3

Now this is plainly wrong, as you effectively have two URLs glued together. Of course the actual URL is the second part:

http://feeds.soundcloud.com/stream/252057321-fantazyfoodtruk-podcast-ep-1-s-1.mp 3

This redirects to another URL but seems to work OK, at least it plays in a browser and doesn't force a download, so correct the URL and you should be OK.

The reason it can't parse your feed is probably because of the faulty URL. FeedValidator objects to it because it begins with https - of course the real URL doesn't. It's no good your submitting it until you've got the URL corrected.
