Just got Chromecast and it is set up, working successfully for YouTube and all the other "optimized" best supported stuff. But not the tab cast.
When I attempt to use it I get the message
Lost Connection to Device - Please check that your device is online.
I'm not exactly sure where to start looking into this. This is really holding me up, because streaming local movies was/is my main motivation for getting ChromeCast and it seems that running a media server and playing in my own browser is the way to go, at least until we get support for VLC or UPnP streams. So frustrating that videos I don't "have" can be played, but those that I do "have" can't be!
Any ideas? Even suggestion towards what direction to further explore would be helpful.
Sorry if the question shows lack of research, but I am kind of at a loss. Have googled it a little but as of yet failed to find anyone with a similar problem. Other streams work so the iptables thing described here: How can I use Chromecast doesn't seem to be the issue. The tab caster doesn't work at all and reports "Lost connection to device" so my problem seems different from purely audio issues like this: No audio while tab casting with Chromecast and Chromium
I am running Chromium 31.0.1650.63 Ubuntu 12.04 and I just got Google Cast (https://chrome.google.com/webstore/detail/google-cast/boadgeojelhgndaghljhdicfkmllpafd?hl=en) a few days ago so that's gotta be current.
