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/6916b304649758361a81968138776daf90d094bc/examples/BFSK_random
You should set ROOT_URL correctly, otherwise the web may not work correctly.
