Thank you for contact us! I'm Anderson, an Independent Consultant and a Microsoft user like you.

good night

it's probably your nat or your friends' nat, do the network test.

What is NAT:

NAT is nothing more than a protocol that translates IP addresses and TCP ports from the local network to the Internet. In other words, the packet to be sent or received from your workstation on your local network goes to the server where your ip is exchanged for the ip of the server and the replacement of the ip of the local network validates the sending of the packet on the internet. When the package returns, the same thing happens, but in reverse. This ensures that the package reaches its destination.

Why is NAT important?

Your NAT type, combined with the NAT type of other players, determines whether you can successfully use multiplayer games or group chats. The following tables illustrate the differences between NAT types. And based on your NAT type, who you can play multiplayer games with, and who you can listen to in a group chat.

OPEN NAT

You can chat with other people, as well as host and participate in multiplayer games with people who have any type of NAT on the network.

MODERATE NAT

You can chat and play multiplayer games with some people; however, you may not hear or play with others and will likely not be chosen to host a match.

STRICT NAT

You can chat and participate in multiplayer games with people who have an OPEN NAT type. You cannot be chosen as a match host.

NAT UNAVAILABLE

You will not be able to use group chat or connect to multiplayer games on some titles on Xbox Live.

Hi Amanda!

Sorry to hear about the issue. Just to confirm, is she the one who can't join your world or you are the one who can't join her world?

I know your other friends can join your world but are her other friends able to join her world as well except you?

Nat type is either strict or moderate, I tried fixing it and went through the web for solutions but none helped to fix it. The thing is I can play all the other multiplayer games with no problem but only minecraft is giving me problem and that too I can
join his world and play but he can't join my world. My Xbox live is logged in and it's working and that is how I can join his world. I don't understand what's the problem with this now. The same problem persists with minecraft pe that I just bought, I can
join my friends but they can't join my game. Note we are not connecting through lan but through multiplayer option, as per the new update which enable us to join our friend's world if they're friends with us in Xbox live. Please get back to me soon, I took
so long to reply as I was trying to fix the NAT type.

firstly check the game settings then check your privacy settings could be a issue with friends that have not added you as a friend not allowing them to join lastly check nat type settings and ask your friends to do the same.

Thank you for the reply.

My settings allow friends and friend of friends to connect.

As i said, when nobody is connected on my world, one person only can join.

Let me explain with an example :

I am in my world

Friend A tries to join my world : success

Friend B tries to join : failure.

Friend A disconnect himself

Friend B ties to join my world : success

Then, Friend A tries to join again : failure.

The problem is that only one person can join me, and nobody else can, no matter who it is.

I am having the same problem, however, for me, it is my friend who is on the Xbox and I am on the Windows 10 version. He cant join the world that I created anymore. He can, however, join me if I create a new world and I can join any of his old
worlds. I Have a theory on what the problem is. We were playing the game fine one afternoon and we both had to get off for a bit to do other things. When I came back it said that my game was updated and some bugs were fixed. From then on my friend can't
join any previous worlds I created but he can join new ones. You will encounter a similar problem on the java edition of Minecraft if you try to connect to a server with a wrong client version. It appears as if the clients updated but the world it's self
did not which is why my friend can't join. That is my theory at least. I did what you said above and it and it still doesn't work.
