Problems streaming video from 4tb wd mycloud

Same problem. Wednesday I had no problems playing mkv or m4v files from my MyCloud 4TB NAS. Today, all I get is tail chasing snake. I can see the MyCloud with no problems via Windows Explorer and my Router menu. Wha’ hoppened?

PS: I just tried playing some MP3 files from my GoFlex NAS and the tail chasing snake popped right up. I even unplugged the WD TV Live and ran the Check Network Connection and I still can’t get the media to play.
