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/8c8cdc5ebd112a88103e91fb02bdd41a8f41f2da/resources/library/interactive/Graphme.wgt/__MACOSX/JavaScript/._AffichageUniboard.js
You should set ROOT_URL correctly, otherwise the web may not work correctly.
