WebUI console flood: AuthError: Not authenticated

[Cas]

I have encountered the following error I think related to the browser displaying 'The connection to the webserver has been lost!'. It occurred after resuming saved state vbox so the lost of network could be a way to replicate.

[ERROR   ][deluge.ui.web.json_api        :207 ] Error calling method `web.connected`
19:15:06.572 [ERROR   ][deluge.ui.web.json_api        :1172] Not authenticated
