Your ROOT_URL in app.ini is https://source.parasitstudio.de:63000/ but you are visiting https://source.parasitstudio.de/wirtz/FixedPointsArduino/src/commit/1f2539ad4b9ddf4acd31e46578e6deda5db2f906/examples/FixedPointCalculations
You should set ROOT_URL correctly, otherwise the web may not work correctly.
