The feedback site (https://feedback.minecraft.net/hc/en-us ) is giving me this error after I tried to log in with my Microsoft account:
namespace "ServiceRuntime"
code "InternalServerError"
message "We don't have right information about user or error fetching the information"
customData {}
I've tried on my PC, on my phone, on several browsers, and in private browsing mode. I've also tried another Microsoft account and by using the link (https://minecraftfeedback.zendesk.com/auth/v2/login/ ) I found elsewhere. I also tried connecting to Microsoft using different methods (the email code method didn't send me an email, but the others seemed to work). I also tried connecting at different days.
I should mention that I've never registered on this site (I don't know if there's a difference between registration and login).
EDIT : While I was trying to log in again, I managed to log in with my second Microsoft account. Why? No idea. I did the same thing as the previous 50 times.
EDIT2 : I've been testing with new profiles on my browser (disposable test profiles to avoid any associated information). I can log in with the second Microsoft account using a blank profile and selecting "Sign in with password." The exact same steps don't work on my primary account. Is it because I managed to log in once by chance with the second account? Is it because my primary Microsoft account has more security features (windows hello) or is no longer linked to my PC? - note : The problem seems to come from "Windows Hello" which is launched automatically and interferes even when a classic password connection is selected afterwards. However, I don't have any further proof beyond that.
In any case, I've spent several hours trying unsuccessfully to log in with my primary Microsoft account (and I have evidence that it's not really my fault), so I believe I can report this as a bug.
Thank you for your work and your help.
This is a known issue that should get resolved in an upcoming deployment.
