MCPE and Windows 10 multiplayer crashing

I always play MCPE on my tablet and then connect to my world on my PC (Win10 edition). Before, I was able to play from my Android Tablet on my PC fine, but now...

My iPad Mini 2 host the game, and crash every 5 - 10 minutes. The message is "This server has restarted!", and the server (or game) closed itselft.

I do not switch app, and I don't close my iPad.

Also, Multiplayer Game and Boadcast to LAN option are on.
