Your ROOT_URL in app.ini is https://source.parasitstudio.de:63000/ but you are visiting https://source.parasitstudio.de/wirtz/FixedPointsArduino/commit/00ce47ffedbb0d3b0bb1f665ae22e48ccae782ce?style=unified&whitespace=ignore-all
You should set ROOT_URL correctly, otherwise the web may not work correctly.
