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/5a9be4593846d42302de6d03020737afd00a9c7b/examples/Switches_float
You should set ROOT_URL correctly, otherwise the web may not work correctly.
