Your ROOT_URL in app.ini is http://git.slaventius.ru/ but you are visiting http://37.143.12.169/test3k/authPostman/src/commit/cf63ef7f811a18a55032924191070e01ed2f62c8/vendor/github.com/segmentio/kafka-go/protocol/findcoordinator
You should set ROOT_URL correctly, otherwise the web may not work correctly.
