Podcast Failed Validation, can't download episodes from your feed

Hi There,

I tried to submit my feed to podcasts connect and I'm getting a failed validation.

It says "can't download episodes from your feed".

This is my feed link, which was created through the powerpress plugin. I'm using wordpress, with the basic theme, and disabled every plugin i can think of that would cause the problem. My audio tracks are cover from my server.

Any idea what I'm doing wrong?

Thanks
