Your ROOT_URL in app.ini is http://git.osmesh.ru/ but you are visiting http://91.221.70.94:3000/MOS/OpenBoard/src/commit/9fce39e6b05ca4470b7b930b5ad96e7d327b5d77/resources/library/interactive/Geogebra.wgt/bin/geogebra_cas.jar
You should set ROOT_URL correctly, otherwise the web may not work correctly.
