Error on DASH stream - pump:Missing or invalid Movie Fragment Box

Having problems with a stream that plays back well on Chrome, Firefox and Android.

Using the most basic players and DRM configuration I get the error:

the error is==>{"category":"mediaerror","clipid":0,"dbgmsg":":pump:Missing or invalid Movie Fragment Box.","errcode":1,"ignored":false,"source":""}

On screen, the video loads, but the "Retrieving" loading bar never completes and no frame of video appears.

Has anyone seen this error before?

<?xml version = "1.0" encoding = "utf-8" ?>
