Hello Mojang technical support! I have a problem! I have mobile wifi router (3g modem),
But when i just want to play on my Minecraft world via LAN (without internet connection, only use wifi ).

I can't join to MY OWN Minecraft world on my mobile device! (pick)
Error message:  "Unable to connect to world. Please check your internet connection to the internet and try again "
But I just want to join to my world on my device !!!
I tried sign out from my Xbox account, - Unable to connect
Even when I tried to create new world it could not  even just  generate world and still show me -Unable to connect.
But there is one exseption: When I turn off ,in world setting "Multiplayer game" . it's ok, then  I can play on my world.
