As this is reportedly still happening in 1.7.x it would be greatly appreciated if any new information about the issue could be posted here, so we can try and reproduce and fix any bugs.

Having same issue here, friends were able to join my multiplayer game (Xbox One to Xbox One, non-realm) for weeks until one day - they now all receive the 'Unable to connect to world' error but I'm still able to join theirs.
My NAT type is open and I have no network issues nor do they, and all our privacy settings with Xbox are unchanged and normal.
All of us are on v.1.8.1 and consoles are up to date, world settings are also invite only and multiplayer is on. Have tried multiple resets, reinstalls etc. across all of us. Thanks.

As of 4/22/19 i am still experiencing this issue. I would love to get this figured out, as i have to resort to paying for a realm for us to play together

Still getting this, it started happening since 1.8 and my friend still can't join my Windows 10 world. And I can't find information to resolve it. It's been too long without a solution.

this is an xbox one thread. this is only happening to me on console. still happening as of 1.11.0

Still happens even in version 1.14 village and pillage and has been happening since release of bedrock edition for me, really would appreciate for the mods to take a look at this for once it’s literally game breaking, I even deleted, reinstalled, switched Xboxes, switched accounts. Changed NAT type to open and still nothing.

I always get the unable to connect error whenever i try to join my friend's world with/without an invite, plus they can't join me with the same error

Me and my friend play in android 1.13 release.
When we try to join each others worlds it says "Unable to connect the world" or sometimes one of us gets stuck on "locating server".
We can both join servers and realms but not each others worlds.There's the possibly that its a bug as we tried lots of things and none of them worked.
Is this an ongoing issue for players on Xbox One in the latest version?

I've had to resort to paying for a realm to have my friends be able to connect to my worlds

@[Mojang] Mega_Spud (Jay Wells) Yes this is STILL an issue on all platforms running the latest version of the game.

On the new Minecraft for my xbox one the game randomly lets my friends join, but later when we try a different world, or that same world it doesn't work. Servers always work.
