How Sign-In Errors Work

If something goes wrong while signing in with Microsoft, Mythrend shows an Authentication Failed page with an error category and a specific message, for example:

Authentication Failed
Error 404 - Minecraft Profile Failure
Perhaps you do not own a license for Minecraft?
If this issue persists, please notify an administrator.

Find your error category below (shown right under "Authentication Failed" on your screen), then match the exact message underneath it.

OAuth Callback Missing

The sign-in process was interrupted before completing. This usually happens if you closed the Microsoft sign-in window early, or denied the requested permissions.
Try signing in again and accept all permissions Mythrend requests.

Microsoft Token Failure

AADSTS70000: The provided value for the 'code' parameter is not valid. The code has expired.
The sign-in link took too long to complete, or was reused after already being used once. Start over from mythrend.net/login.

Unable to convert refresh token to MC token. Please try again later.
A temporary issue refreshing your session with Microsoft. Try logging out and signing in again.

Other AADSTS codes / Unknown error.
These messages come directly from Microsoft and can vary. Starting the sign-in process again resolves it in most cases.

Email Request Failure

User does not appear to have a visible email address.
Mythrend needs permission to view your account email. Make sure you accept all permissions on Microsoft's consent screen, including profile and email access.

XBL Authentication Failure

Unable to authenticate XBL from MC refresh token. Please try again later.
A temporary issue communicating with Xbox Live. Wait a few minutes and try again.

XSTS Authentication Failure

The account is banned from Xbox.
This account has an active Xbox Live ban, resolve it directly with Microsoft/Xbox Support.

This Microsoft account does not have an Xbox profile.
Visit xbox.com, sign in with the same account, and complete Xbox profile setup. Then try Mythrend again.

Xbox Live is not available in this region.
A Microsoft restriction tied to your account's region. This can't be bypassed through Mythrend.

Adult verification is required on the Xbox account.
Visit xbox.com and complete age verification, then try again.

This is a child account and must be added to a Family by an adult.
An adult needs to add this account to a Microsoft Family group before Xbox services can be used.

Unable to generate XSTS Token / Unable to generate XSTS user hash. Please try again later.
A temporary issue during the final Xbox authentication step. Wait a few minutes and try again.

Minecraft Authentication Failure

Unable to generate Minecraft Access Token from XSTS. Please try again later.
A temporary issue exchanging your Xbox token for a Minecraft token. Wait a few minutes and try again.

Minecraft Profile Failure

Perhaps you do not own a license for Minecraft?
Mythrend couldn't find a Minecraft Java Edition profile on this account. Make sure you've purchased Minecraft Java Edition with this Microsoft account and launched the game at least once.

Malformed JSON response for Minecraft Profile. Please try again later.
A temporary issue retrieving your Minecraft profile. Wait a few minutes and try signing in again.

Unknown or Unlisted Errors

Most errors above resolve themselves by simply trying again. If an error persists after a few attempts, or you see a category or message not listed here, email us at [email protected] with a screenshot so we can investigate further.
