Your ROOT_URL in app.ini is http://git.osmesh.ru/ but you are visiting https://git.osmesh.ru/MOS/OpenBoard/blame/commit/aad98a67259c1ef64c57c250a0b68e933fa299b8/resources/etc/npapi-wrapper.application.x-shockwave-flash.swf.htm
You should set ROOT_URL correctly, otherwise the web may not work correctly.
