I get the error ''Unable to connect to the world'', my friend is user of the Pocket Edition version and also he tries with the Windows 10 version, i can enter in his world and the world of my other friends, also he can enter to the world of other friends, but no to my world.

This problem appeared on January 6, 2020, before we could play together without problems.

Sorry for my English, it's not my native language
