Error 80151011 occurs when you try to sign in to Xbox LIVE

You see the following error message and code when you try to sign in to Xbox LIVE:

Sorry, Xbox LIVE profiles can't be downloaded right now. Please try again later. 
Status code 80151011

This may indicate a problem with your profile.

Solution 1: Did you recently sign up for two-step verification?

If you recently turned on two-step verification, you may not know how to sign in to apps or devices that don't accept security codes. Some apps (like the mail apps on some smartphones) and devices (like the Xbox 360) can't prompt you to enter a security proof when you try to sign in. If you get an incorrect-password error with an app or device, you'll need to create a unique app password to sign in. After you sign in with your app password, you're all set to use that app or device. You’ll use this new app password to sign in to your device instead of using your Microsoft account password.

You'll need to create and sign in with an app password once for each app or device that can't prompt you for a security proof.

1. Sign in to your Microsoft account.
2. Under Password and security info, tap or click Edit security info. 
   If you're prompted for a security proof, enter it and tap or click Submit.
3. Under App passwords, tap or click Create a new app password. 
   A new app password is generated and appears on your screen.
4. When you’re prompted for your Microsoft account password on your Xbox console, enter the app password that you created online. 
   After you sign in with your app password, you're all set to use that app or device. You will use this new app password to sign in to your device instead of your Microsoft account password.

Solution 2: Verify your Microsoft account security information

Follow these steps:

1. Visit Microsoft account. If you forgot your password or it doesn’t work, reset your password.
2. Click Edit security info.
3. Verify your security information. For example, verify the Phone number, Alternate email address, and Security question information.
4. Sign out of your Microsoft account, and then sign in again.
5. Try to sign in to Xbox LIVE again.

Solution 3: Clear the system cache

1. Press the Guide button on your controller.
2. Go to settings and select System Settings.
3. Select Storage or Memory.
4. Highlight any storage device, and then press Y on your controller. (It doesn't matter which storage device you select; the cache will be cleared for all storage devices.)
5. Select Clear System Cache.
6. When prompted to confirm storage device maintenance, select Yes.

Solution 4: Move and then redownload your Xbox LIVE profile

Note If you want to use a USB flash drive or a USB hard drive to complete these steps, you must format the USB flash drive or USB hard drive for Xbox storage. (See USB flash drive support for Xbox 360.)

   3. Select All Devices.
   4. Select Profiles, and then select your gamer profile.

   7. Remove the Memory Unit from your console.

The Microsoft account associated with this account is not valid

If you get this error message, it may mean that your Xbox LIVE gamertag is associated with a non-valid Microsoft account. To resolve this problem, you'll need to associate your Xbox LIVE gamertag with a valid Microsoft account.

2. Select Continue.
3. Enter the email address and password of the Microsoft account that you want to associate with your gamertag.
4. Confirm that the Microsoft account information is correct.
5. Accept the Xbox LIVE Terms of Use and Privacy Statement. (If you select Decline, your changes will not be saved.)
6. Complete the changes and return to the Xbox Dashboard.
7. Sign in to Xbox LIVE using your gamertag.

If you still can’t sign in, contact Xbox Support.

Xbox LIVE sign-up or account download is currently unavailable. Please try again later. 

To resolve this problem, try the following solution

1. Check the Xbox LIVE service status at Service status.
   • If there's a service alert, wait and try again later.
   • If there are no service alerts, try the next step.
2. Test your Xbox LIVE connection. Here's how:
   1. On your console, go to settings and select System.
   2. Select Network Settings.
   3. Select Wired Network or your wireless network name (if you're prompted to do so).
   4. Select Test Xbox LIVE Connection. 
      If you can’t connect to Xbox LIVE, sign in with your Xbox LIVE gamertag.
   If after trying this procedure you still can’t connect to Xbox LIVE, try the Xbox LIVE connection error solution.

Solution 1: Make sure that you are using the right Microsoft account

If you have more than one Microsoft account, make sure that you use the right one — the one that was used to create your Xbox LIVE account. If you forgot, see Manage your Microsoft account.

Note If the Xbox LIVE account is a child account, make sure that you enter the child's Microsoft account.

Solution 2: Check your Microsoft account on Xbox.com

To make sure that the Microsoft account you are using is the right one, try signing in to Xbox.com by using the same Microsoft account that you are trying to use on your console. If there’s a problem with that Microsoft account, you are prompted to correct it.

If you are signed in with an incorrect gamertag or if you are prompted to create a new Microsoft account, you are likely using the wrong Microsoft account.

Solution 3: For a child’s account, use the child's Microsoft accoun

If the Xbox LIVE account is a child's account, make sure that you enter your child's Microsoft account. You must use the Microsoft account that was used to create the account

If your child's Microsoft account was automatically created as part of Family Account setup and you try to reset the password, email is sent to the Microsoft account parent account (the Xbox LIVE family primary account). Follow the instructions in that email to reset the child's account's password.

If you only want to download the account profile, use the Download Profile feature when you are signed in with the Xbox LIVE family primary account.

Solution 4: Reset your Microsoft account password

If you can’t remember your Microsoft account password, try resetting your password.

Solution 5: Go to the Windows Solution Center

If you can’t reset your Microsoft account password, go to the Windows Solution Center for help recovering your password. Xbox Support can’t reset your Microsoft account password for you.
