Start at the Ui.UiServer startup shown in the report, where the web interface binds to http://127.0.0.1:43110/. Review how the UI listen address and port are configured, including the NAS environment and port-80 access. Done means the web UI can be reached as intended from the NAS setup, with the relevant behavior covered or documented.
