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/c1ee274e118ea48e472d5741aa9312152b9e9120/resources/library/applications/Wiktionnairy.wgt/script/languages.js
You should set ROOT_URL correctly, otherwise the web may not work correctly.
