Live stream does not work

[test343]

Even example with live stream does not work:

http://dashas.castlabs.com/demo/try.html
http://dashas.castlabs.com/videos/bytes/bbb/Manifest.mpd

Аfter playing some time player shows error.

In my project I alsow tried to set up live stream and play it with dashas with the same result.
