Your ROOT_URL in app.ini is https://source.parasitstudio.de:63000/ but you are visiting https://source.parasitstudio.de/wirtz/FixedPointsArduino/src/commit/d2a63faf53f3545085bfad0ed78c7e700e0b9a61/examples/FixedPointCalculations
You should set ROOT_URL correctly, otherwise the web may not work correctly.
