We have a simple setup on Wowza Cloud streaming to the Wowza Player with Apple HLS. A pretty standard setup.
The player works in all browsers except IE 11 on Windows 7. IE 11 loads a flash version of the Wowza player.
The issue with the flash player is, that after initiation an error is shown: Stream Unavailable.
Its hard to debug as the player is flash and no errors are given on the command line.
