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/8a9edb36cc3390e23f04c9cad86b6ac930b75eaf/resources/library/interactivities/Train.wgt/js/help-template.js
You should set ROOT_URL correctly, otherwise the web may not work correctly.
