AppleTV streaming worked. Then it didn't. Help!

Only discovered Network Stream yesterday. Immediately put some stuff into the iCloud drive. First two episodes streamed perfectly. None of the others will. They're all encoded the same, as far as I can tell. Is there anything else I can check to get this working?

Same thing has happened to me, since the recent updates I can no longer stream files from my PC. Works in Amazon Fire Stick VLC but no TVos.

My not so very scientific testing leads me to believe that the links expire and you need to put new ones in.
