Home Share disconnects on ipad air after a few minutes of play

So I upgraded to ios 9.1 on all my devices and running El Captain on my mac mini. I try and home share on my ipad air and the share button works I hit a movie and then after a few minutes it crashes and kicks me out back to my video app and list on movies but home share is no longer on or available and I have to close the video app and restart it to get the home share button back.

I have tried the following:

I have restored the ipad air to factory settings.

I have called Apple care

I have signed out of icloud and itunes and back in on the mac mini and the ipad air

I have gone into the mac mini network options and made sure that my wireless network is first in the list for all devices

I have made sure all devices are on the same apple ID and network.

I have restarted my ipad air and mac mini

HEEEELLLLLLLPPPPPPPPPPPPPP
