Just in the last couple of days 2 laptops I have been using with chromecast now come up with "failing to cast" message when connecting to found device. This is happening on more than one chromecast and is happening on both laptops (Running Windows 10). Iphone and desktop connections work 100%. Has anyone else struck this problem? Wanted to use this for casting Spark Sport...it has been working fine with all sites but just all of a sudden won't cast
