Error to connect friends worlds!

Good morning Good afternoon Good night! I'm here because I'm a player of the original Mcpe! And I'm here to complain about a Bug that always happens, that the error "It was not possible to connect to the world" This error happens whenever I try to play with my friends, and nowadays it is unbearable, it happens always and always! I can't play with them anymore! So I humbly ask you to fix this error in the next update! Thank you very much in advance!
