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/687b65658c592b9ddf5b883de627999dda0d19e5/resources/library/interactivities/Train.wgt/js/help-template.js
You should set ROOT_URL correctly, otherwise the web may not work correctly.
