Your ROOT_URL in app.ini is https://source.parasitstudio.de:63000/ but you are visiting https://source.parasitstudio.de/parasiTstudio/BALibrary_parasitstudio/commits/branch/feature/AudioEffectAnalogChorus/examples/Tests/BaudrateTest/BaudrateTest.ino
You should set ROOT_URL correctly, otherwise the web may not work correctly.
