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/ca762f4274596559d54875a301c3ecdc9f85d14c/resources/library/interactivities/Train.wgt/js/help-template.js
You should set ROOT_URL correctly, otherwise the web may not work correctly.
