Your ROOT_URL in app.ini is https://source.parasitstudio.de:63000/ but you are visiting https://source.parasitstudio.de/wirtz/OpenAudio_ArduinoLibrary/src/commit/db4e8ad35ca02de8ad1e93d48323fddf80719bd1/docs/audio_f32_html
You should set ROOT_URL correctly, otherwise the web may not work correctly.
