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/c9680a304cef9f99662972a39e3dc68fea0c26f0/examples/Switches_float
You should set ROOT_URL correctly, otherwise the web may not work correctly.
