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/8fe3dce0d2ee52678f98ecdbc556053a6d13dea1/resources/library/interactivities/Train.wgt/js/help-template.js
You should set ROOT_URL correctly, otherwise the web may not work correctly.
