It is possible that the vbox issue is the same one as identified occuring when DVR setup data has old TiVo lineup - see Unexpected error when going to Live TV & DVR Settings - #72 by sa2000
There appears to be a Plex Web DVR Setup bug leading to the message “There was an unexpected error” when selecting Live TV and DVR Settings
This is not a VBox specific issue but is a general issue if the server DVR data in the media_provider_details table has a no longer existing lineup
Do we have debug server logs covering the time of the error for the VBox ?
The issue with no longer existing lineups giving this error has been referred to the Plex Web development team and I expect it to get looked into in January
(Please note that the Plex Web hosted app (via https://app.plex.tv/desktop) has correction to other setup issues for Vbox that the bundled Plex Media Server Plex Web app (via http://ip-of-server:32400/web) does not have - so any setup ought to be done using the hosted app)
