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/8f091dad1ec0416f8f51c84d6264e2bfbb77f5c7/examples/Switches_float
You should set ROOT_URL correctly, otherwise the web may not work correctly.
