You cannot use the same microsoft account on 2 different devices to play LAN anymore

This report does not have enough information for us to understand and reproduce the problem.

At what point are you getting the error?

What do you mean by a “license for bedrock”? The license is based on the type of “device”, (Windows, Xbox, Android, etc).

What kinds of devices are you using, how are you connecting, etc?

Can confirm (came from MCPE-237415), Affects 26.10 using Windows to iOS, and iOS to iOS.

Steps to reproduce:

1. Make sure you have 2 devices with the same Microsoft Account, and has connected to the same Wi-Fi network

2. With Minecraft open on the first device, click Play

3. Open a world with multiplayer enabled

4. With Minecraft open on the second device, click Play

5. Join the LAN World hosted by the first device

Expected result: The second device should join (and third and beyond if any)

Observed result: The second device gets kicked with “An error occurred“, Blaze error (just because it was linked to the same Microsoft Account).

Workaround: Sign out of the Microsoft Account on other devices so only one of them uses it.

I also noticed it happening between ipad and pc, and between ipad and another ipad. Initial connection 44 is the error it shows regardless of the platform

I am having the same issue. Prior to 26.10 update I have been playing on both PC and IOS using the same Microsoft account on LAN hosted by the PC. Upon the IOS device joining it would be given the username(1) tag.

Post 26.10 update, attempting to join the LAN world on IOS results in the “Blaze” error code. Even when signing out of the Microsoft account on IOS and signing into a different Microsoft account on IOS the same issue persists.

Steps to reproduce:

1. 2 Devices, 1 on PC, 1 on IOS, signed into the same Microsoft Account, on the same Wifi, running version 26.10

2. PC device loads a world, available on LAN

3. IOS devices attempts to join LAN world

Expected result:

IOS device joins PC device’s world via LAN, given the Username(1) tag, with seperate inventory. IOS device can freely leave and re-join world, maintaining inventory.

Observed result:

IOS device cannot join PC LAN world, presented with “Blaze” error code. (see attatched, image 1)

Image 1, IOS screenshot of “blaze” error code presented upon attempting to join PC LAN world whilst both devices are signed into the same Microsoft account

Workaround:

None, even after signing into a different Microsoft account on the IOS device, attempting to join the PC LAN world is unsuccessful, given the same “Blaze” error code (see attatched, image 2).

Image 2, IOS screenshot of “Blaze” error code presented upon attempting to join PC LAN world after signing out of the Microsoft account shared by the PC device and re-signing into a different Microsoft account on the IOS device.

Further attempts to workaround:

I have on several occasions signed out of the microsoft account on both devices, restarted both devices, restarted Wifi and Checked firewall settings on PC for Issues. I am at a loss for issues on my user side that could be causing this.

Workaround: on one device, sign out of your account and then restart Minecraft. This allowed me to LAN connect from iPhone to PC.

The change that is making this workaround necessary to join a LAN world is incomprehensible, because LAN connection doesn't even use the MS account! It is just Microsoft engaging in cumbersome gatekeeping for no purpose. Indeed, it’s practically a privacy violation, because the game shouldn’t even be checking your sign-in status for a LAN connection.

Also, disconnecting the Microsoft account on either devices still gives this error. This is not about the accounts.

We did report this issue to Mojang, and they said it was working as intended, so the report was closed as such. The decision to close a report as Works As Intended is always made by Mojang, not us.

I can assure you there are many players frustrated by this, especially in households that bought the game through the same Microsoft account on different devices that can no longer enjoy the game together. It had functioned like this for many years, I have been able to do this since late 2021 and have used it to run advanced farms in multiple dimensions. I, like many players, have lost valuable items in accounts that I am now locked out of because this bug is not being fixed

Can I ask to hear WHY they believe this issue should be left alone and not fixed? I understand that you shouldn't have two people on the same account, but this is over a LAN world and not something like a server or Realm where it matters. This is also in parity with Java - they also cannot join on the same account on a LAN world.

I believe not reverting the change could raise some? legal issues because people are being forced to buy the game again in order to play on multiple devices in the same household, because I know some platforms do force the Microsoft account that you bought the game from onto the player. I don't know much, but it is similar to the migration issues

This should NOT be marked as “working as intended” as this is a feature that’s been working fine for who knows how long. I’ve been playing with my wife on a world hosted on my Xbox, and I’ve been joining from my phone with the same profile on both. For some reason though, it’s been decided that the same profile can’t be used for this anymore, and you get the same blaze error that tells you basically nothing every time. I think it’s a terrible change that winds back years of a feature that was never broken, and it’s extremely unprofessional of everyone involved that keeps saying this issue is “working as intended” and ignoring the community. This change should really be roll back as soon as possible as it literally stops people from being able to play the game as it was always intended to be played

I appreciate that you guys have your hands tied by Microsoft here, but I've got no better place to express my significant frustration on this too. We have long played as a family via split screen on X Box and with my daughter on a phone and then iPad (and I bought additional copies of the game for the device each time) in the lounge, but now her player of many years is stuck in the digital aether, with her inventory gone and all of her animals wandering around our world unable to be controlled by anyone. She's devastated. If it wasn't broken, why fix it? And if this change does have to be made, then maybe at least provide a tool to transfer player data to a new Microsoft account.
