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/61b7b76e3017d927ff92a53a2f847b32272c5811/resources/library/applications/VideoPicker.wgt/scripts/languages.js
You should set ROOT_URL correctly, otherwise the web may not work correctly.
