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/d4d5d38cd8895b4955b2a7b526d21d7c4d892fa7/resources/etc/npapi-wrapper.application.x-shockwave-flash.swf.htm
You should set ROOT_URL correctly, otherwise the web may not work correctly.
