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/48db1010c48b5c47990b86e440871314d37f5dd6/examples/Switches_float
You should set ROOT_URL correctly, otherwise the web may not work correctly.
