Login Failed

[st4xy]

Since December 20, it has not been possible to log in using the "This Device" button. I checked on two versions of Minecraft, 1.19, 1.8.9. Disconnected VPN. reinstalled the client and the error does not go away. 24 hours ago everything worked.

I'm having the same problem. To quote my comment on the curseforge project:

As of recently, I've been getting "an unknown error occurred" when I try to authenticate using the "this device" option, no matter how many times I retry. Any idea what that's about?

The log says:

somthing is already using the port ReAuth is using to receive the Microsoft authentication. Please use the "Any Device" option for now.
