MCPE and WIndows 10 edition worlds do not appear

When world is running with Mulitplayer Games and Broadcast to LAN switched on, on both Window 10 Beta edition version 0.14.3 and Ipad 3 ME version 0.14.3, the worlds do not appear on the other device/computer.

I have tried:

• turning off firewalls
• restarting all wifi routers, devices, computers
• being patient
• Hosting on iPad, hosting on windows 10 computer
