Your ROOT_URL in app.ini is http://git.osmesh.ru/ but you are visiting https://git.osmesh.ru/MOS/OpenBoard/src/commit/5cf432070726b574d8d45c293281525b59e5eef3/resources/library/interactivities/Tables.wgt/css/images/slate-toolbar-reload.png
You should set ROOT_URL correctly, otherwise the web may not work correctly.
