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/41b634fbdf863895e1241ee2fd1cbeb7d34c2cc5/docs/audio_f32_html
You should set ROOT_URL correctly, otherwise the web may not work correctly.
