Your ROOT_URL in app.ini is http://git.osmesh.ru/ but you are visiting http://91.221.70.94:3000/MOS/OpenBoard/blame/commit/d66633a0b1fe366573b452acc4a54e7165e988ae/resources/library/applications/Wiktionnairy.wgt/script/languages.js
You should set ROOT_URL correctly, otherwise the web may not work correctly.
