Your ROOT_URL in app.ini is https://source.parasitstudio.de:63000/ but you are visiting https://source.parasitstudio.de/wirtz/FixedPointsArduino/src/commit/2ad0e02e3d22bbc796b80dc1f85271678b0f6959/examples/FixedPointCalculations
You should set ROOT_URL correctly, otherwise the web may not work correctly.
