Ever since this stopped working for me I just gave up and thought it
must be my devices and/or software. ENOTIME.

Interesting... Although it doesn't work for me atm, I think I've seen
the exact behavior in the past.

Are you on 3.10.50-1?

It could, maybe are devices that multicast dlna but they serve only on the
same network, for some unknown reason. But I don't know how to debug that.
I'd be happy enough to see the multicast ping work or some other test that
validate the network config before moving into devices.

Anything I can try comes to your mind. I've some time for this atm, don't
know how long it will last.
