Your ROOT_URL in app.ini is https://source.parasitstudio.de:63000/ but you are visiting https://source.parasitstudio.de/wirtz/MicroDexed/blame/commit/c944ffa1e3f389bec20ec0aac93532a1eec921eb/third-party/ArduinoJson/extras/tests/JsonSerializer/std_string.cpp
You should set ROOT_URL correctly, otherwise the web may not work correctly.
