Hello. I would like to report a bug that happens each time I try to join two specific worlds. It started to happen a week ago, and it is a very constant and confusing bug. Of course, is normal for it to happen anytime, but is happening EVERY time I try to join and just in those worlds. It gives the message "unable to connect" or "no ha podido conectarse" in spanish.

One world is totally Vainilla, and it has been working normaly for a year before this. The other one includes mods and add-ons, but it also worked pretty well until this. He hasn't added anything new to it.

I have tried everything: telling them to restart, restarting, reinstalling minecraft, deleting data, changing wifi... And nothing have worked at the moment. My internet is pretty decent and I am able to join to other worlds and servers without problem. Thanks.
