Error: AuthenticationException: Migrated

GLENNpm · Aug 9, 2022

Hi! I just transferred all my Minecraft java edition files to a new SSD. Everything is copied over with no problem from what I can tell. But when I try to log in to the launcher, I get this message: "Sorry, but we couldn't connect to our servers. Please make sure that you are online and Minecraft is not blocked. (AuthenticationException: Migrated)".

I'm using my Microsoft login information. When I tried to use the old Mojang info, I was told I had the wrong username/password. I've verified that java isn't being blocked by my Windows Firewall. I'm not sure why that would even matter or why I'm even getting this message, though, because I'm not trying to connect to servers or get online at all. It's all local. Yet I can't even access the launcher, itself.

:)

Thanks for the update!
So, are we good now Glennpm?

I'm on Windows 10. In addition to what's already listed, I have now backed up my files, deleted .minecraft, and downloaded the installer from minecraft.net again. Now I can't even install the mc launcher. I can download the installer. But when trying to use it, it tells me "Looks like something went wrong. We weren't able to install the app (0xUnknownAppInstall)."

Then I uninstalled Minecraft completely from Apps & features and restarted my PC. I still receive the same error when trying to use the installer from minecraft.net. In the Microsoft Store, it shows that I already own Minecraft. When I click the install button there, it's unresponsive.

When I try to install it from the Xbox app, I receive a new error code:1x00000001.

I'm unable to try other accounts at this point since I can't even install the game anymore.

Hi and thanks for reaching Microsoft Xbox gamer's community. My name is Josef.
I'm an Independent Advisor and a Microsoft Xbox user like you.

Hope you're doing great today despite this GlennPm

Please answer the following questions :

Is this happening on Windows 10 or 11?
May I know which launcher are you using? The one from Microsoft Store or a different launcher?
If you try using a different (or dummy) Microsoft account. Are you able to access or the same message appears?

And, beside the troubleshooting steps provided in the post. Which else did you tried?
In that way I can advise you different things or how to proceed

I'll be waiting for your feedback, greetings

I fixed it by updating the optional updates to Windows and reinstalling everything from scratch!
