[MCPE-190764] New UI will only show one LAN game, at random

It is normal in our scenario to have multiple LAN games running (via BDS), and prior to the 1.21.60 UI “Play menu” update, all of the local BDS servers always showed up fine. When the new Play menu update took effect, it now will only show ONE of the LAN servers, seemingly at random.

I have run two copies of 1.21.62 in Windows, side by side, one with the new Play menu rollout, and one without, and the old menu will always show ALL the games, while the new one will only ever show ONE of them.

This seems to be a new bug introduced by the menu update.

Hello and thank you for your report!

However I was not able to reproduce this issue.

Could you provide a video/screenshot and informations about the platform (system specifications, BDS version etc.)

This will help us better understand and hopefully reproduce the issue.

Client version is 1.21.62 on Windows 10/11.

BDS server version is 1.21.62.01 on Ubuntu. 4 servers running, each on a unique IP, all on standard port 19132.

Clients and servers all on same subnet.

The OLD UI shows all 4 servers (and always has), with no issues whatsoever:

[media]

The NEW UI will only ever show ONE server, and if the client is restarted, it will cycle to any random one of the 4 servers at random, but never shows more than one.

[media][media]

It makes no difference if the server-name is changed, I’ve set them to different names and the behavior in the client is identical.

Not the OP but here is a video showing this: https://youtu.be/MaPEBTORM5g If I join a game and exit out, it seems like it changes servers as to which one shows up. I have six minecraft servers running on my LAN and I’ve changed nothing about how the servers have been configured.

Hello again!
We would appreciate information if the servers are being run on one host or different hosts across your LAN network? If you managed to run a few BDS from one host, could you explain how you did it?
This information will help us evaluate the issue!

Tofulisk 2025-03-13T18:28:41Z

From the LAN view, each BDS server appears as a unique host (each has a unique MAC/IPv4) on the LAN, and all are exposed through port 19132.

Internally, each BDS server is a Docker container running on the same Linux host, attached to a macvlan network in bridge mode, but this is transparent to the outside LAN world.

I have the same problem and Docker container setup like Tofulisk. Containers are separate IPs (192.168.1.50:19132, 192.168.1.51:19132, 192.168.1.53:19132). Worked fine on older versions with old UI.

I see the same issue with Bedrock 1.21.62 on Android client . Similar behavior on X-Box client

When the Worlds tab loads, either

one LAN game is shown from however many are really running, or
none are shown

If (2), then setting LAN worlds to hidden, and then back to shown (top left of worlds tab) will show one LAN world (just like case 1)

However, if you change to Realms tab, and then back to Worlds, no LAN games will be shown again (toggling LAN world hidden button no longer has any effect). Go back to the main menu (Play / Settings / Marketplace) and back in again, and you are back at the top of this loop.

It doesn’t appear to matter what or where the LAN games are. Same behavior for

multiple custom servers (running on windows)
multiple games on different local devices (1 X box, 1 Switch, 1 android phone)
Combinations of the 2 above

Network monitor shows that Raknet pings and pongs are being sent as expected between devices - so the actual discovery process looks fine - i.e. it looks like a UI issue.

If literal commands are helpful, here is what I do:

# create macvlan network (in my case, my network is a /22 and my network interface of my server is ens7f1)
docker network create -d macvlan --subnet=192.168.0.0/22 --gateway=192.168.0.1 -o parent=ens7f1 macvlan1

# here's an example of 4 servers I have on my LAN where I am manually assigning unique IPs:

To provide an additional data point, I started another minecraft server on a completely different machine on my network, also using a Docker container. I wanted to see if it would show one random server from each server or if it would continue to only show one. From my test, it only shows one random server, no matter how many containers I create on each server or on how many servers I create them.

Nopey 2025-03-22T22:39:53Z

I have the same problem of only 1 LAN server appearing and disappearing.

Running 3 seperate Ubuntu servers with separate IPs and standard port and having the issue in all my Android and Windows clients.

Marian L 2025-03-23T08:06:43Z

Same issue. I am running 5 bedrock servers via Docker on Unraid. I can manually join each server in the Servers tab by entering the IP/port, but only one server shows up in the Worlds tab.

Tommy Newman 2025-03-24T19:18:16Z

Do we know if this is going to be fixed in the spring to life update tomorrow? I’ve also had the issue on my Ubuntu server running docker Minecraft servers.

This issue was not addressed in the 1.21.70 update, and continues to occur in that version as well.

Matt Bentley 2025-04-05T01:10:03Z

Well I had no idea you could manually connect to a server. At least there is a workaround. It’s pretty ridiculous that this has been broken since February. Can we at least get an option to go back to the old menu that actually works?

Brad Engels 2025-04-05T02:06:48Z

This appears to be fixed in preview 1.21.80.25. I can now see all my LAN games.

Tommy Newman 2025-04-28T14:25:07Z

Do we know when the update will be released to live to fix this?
