Webplayer 5 not loading in mobile view

Hi,

the Webplayer does not load in mobile view.

I am using Wordpress 5.5.1, Podlove Web Player Plugin 5.2.9 and Podlove Podcast Publisher 3.0.2.
I set up a custom “configuration”, “theme” and “template” as a default.
The Webplayer ist not loaded automatically but using a podlove-template in each episode.
The podlove-template includes the webplayer via {{ episode.player }}.

The following screenshow show, what the browser tries to load for the webplayer.
Clearly, a wrong url is given for the scripts.

How can I make this work?
