Your ROOT_URL in app.ini is http://git.osmesh.ru/ but you are visiting https://git.osmesh.ru/MOS/OpenBoard/src/commit/82e5f92ca611f19c83ab7e07fc9aad4201d2384a/resources/library/search/Video%20Planete.wgs/icon.thumbnail.png
You should set ROOT_URL correctly, otherwise the web may not work correctly.
