Files cannot be delivered it

I am running in a curious problem. I have set up a new Wordpress with podlove to start a new podcast. I am running with pretty much the same settings and at the same hoster another podcast-wordpress.

Everything seems fine, but neither the web player of podlove nor any other podcast player can find the files and play them. I am using the same cdn though as with the other podcast and they are in the same directory. Using the direct URL delivers the files.

Here is a debug info from the podlove plugin. I just do not know what setting can be wrong. Could there be some Wordpress plugin interfering?
