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/ac51989b45e0fb57e3f43f0935529f6d6a4d477d/resources/etc/npapi-wrapper.application.x-shockwave-flash.swf.htm
You should set ROOT_URL correctly, otherwise the web may not work correctly.
