Have the same problem but Gen2 Chromecast on win10
All casting in tabs ok.. Android, tablet etc..
But go to the videostream tab and trying results in this message:
"Unable to cast to device.
An unexpected error occurred. Please try the following:
Try to cast again
Verify your network connectivity"
Well trying again does the same and it works with everything else but not the videostream tab.
This is the log that is generated during the error:
