Was playing this morning, went out , came home, and Videostream won't connect anymore.
Updated Chrome
Restarted and reinstalled my Chromecast
Deleted and reinstalled videostream
Installed the 'Launch Videostream'.. little thingy
Restarted computer (ubuntu, no firewall issues - apparently...either way I haven't done any updates)
Tried casting other tabs - no problem. Only Videostream not connecting.
chrome://restart
Never had this kind of problem before...
