Your ROOT_URL in app.ini is http://git.osmesh.ru/ but you are visiting http://91.221.70.94:3000/MOS/OpenBoard/src/commit/f8ace64ec1882e76fcc56ca50348e52de85382c0/resources/library/audios/Animaux/mammiferes%20sauvages/lion.mp3
You should set ROOT_URL correctly, otherwise the web may not work correctly.
