AI Summary: The user is unable to connect to an embedded NUT server on a Unifi UPS-2U using the `nut_webgui` Docker image, despite successfully connecting via the command line. The web GUI reports the UPS as 'DEAD', indicating a connection issue between the Docker container and the UPS's NUT server.

AI Summary: The user is experiencing connection issues with their Network UPS Tools (NUT) web GUI (nut_webgui) after upgrading to version 0.5.0. The GUI fails to connect to their Synology NAS-based NUT server, returning an "UNKNOWN-COMMAND" error. The previous version (0.4.2) worked correctly. The task is to investigate why the upgrade broke compatibility with the Synology NAS NUT server, potentially focusing on changes in the OpenAPI specification or Synology's limited NUT implementation. Debugging will involve analyzing the provided logs and potentially testing with a standard NUT server to isolate the problem.
