Links with access denied

I created an audio feed for this channel and subscribed using Pocket Casts app. For some reason, the app cannot download some links (videos with length greater than 40 minutes), because it is forbidden. For example:

<link>http://www.youtube.com/watch?v=374SgPGPtjo</link>
<title>Decrépitos AO VIVO - Vortando das Férias</title>

I tried to access http://youcast.cloudapp.net:80/FeedService/Audio.m4a?videoId=374SgPGPtjo using Chrome and it says

You don't have authorization to view this page.

I did manage to download this specific audio file. Maybe you can too now? The audio feed (and all YouCast) is basically a "best effort". It works when it works and when YouTube blocks it there isn't much I can do (as far as I know, at least).
