Hi @ivanchevskaya Thank you for the report, I filed this bug report [DocDB] yb-master/yb-tserver fail to start when –webserver_password_file is set (Web UI auth) · Issue #32074 · yugabyte/yugabyte-db · GitHub . ivanchevskaya: Also, is there any currently supported way to enable authentication for yb-master and yb-tserver Web UI ports 7000 and 9000 , or is the recommended approach to protect these ports using an external reverse proxy/auth layer? A reverse proxy is the recommended approach for now.
