Problem to publish my first episode

Good Evening!
I am new with Podlove.
I have managed to publish my first episode however I have a problem.
When selecting the audio It finds the slug verifys it and plays. However when I publish it and select play. It will not play it says:

“Error loading audio files Couldn’t load the audio files from the server. Please try again later”

The mp3 link works when I click on the edit part of the episode.
Can someone help me? It would be great!
