OpenBh 5.6 & Vu+ Zero

[_Gigino_]

For two days and three nights now, I haven't been able to resolve the problem you see in the video (a video is worth a thousand words!).
The Vu+Zero, like the Vu+Solo2, is connected via LAN cable and the network works.
Besides the offline feed, what could the problem be, if there is one?

. . . and the problem persists even with the latest version (5.6.003).
Is it possible that the feeds have been under maintenance for almost a week, or is there a problem with my Vu+ Zero?
