Server disconnected.

I try to play Minecraft PE 1.1.0.4, with my cell phone Samsung Gran Prime (Android 5.1) or Tablet Samsung Tab 2, together in Windows 10 Edition 1.0.6, and when I connect the cell phone or tablet, the "server disconnected". And then I can not play, I can only play if it is in Minecraft PE against Minecraft PE. Now if I try to play Minecraft PE against Minecraft Windows 10 Edition from the 'disconnected server'. What should I do to fix this error?
