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/c8291c2d323857e90ffa9469dc75cf80ff81ef2f/examples/ToneDetect1
You should set ROOT_URL correctly, otherwise the web may not work correctly.
