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/c2dcd3b95d74516009ba9bf4a292fe23a3381ec1/resources/library/interactivities/Train.wgt/js/help-template.js
You should set ROOT_URL correctly, otherwise the web may not work correctly.
