Error code:0x80a40403

All sorted for now thanks guys x

hi there i would suggest if the steps below dont work head over to https://support.xbox.com/ and chat to an advisor there to walk you through the steps in the mean time

If you’re receiving this error code when trying to sign in with a child account, it may mean that the child account isn’t a member of your family.

Child accounts that aren’t members of a family won’t be able to use the Xbox Live service until they’ve been added to a family. To verify whether the child account is a member of your family, sign in to your Microsoft account and see if the child’s
account is listed on the Your family page.

Sign in to your account

If the child account is a member of your family, go to the next solution. If the child account isn’t a member of your family, you’ll need to add them so they can sign in and use Xbox Live. For info, see:

Add family members on Xbox One

or

Make sure that your privacy settings are set so that the child account can sign in. To do so, have the child sign in to their account at www.xbox.com. Then, when prompted, the adult account associated with the child account should sign in to www.xbox.com
and give permission for the child account to sign in to Xbox Live.

Sign in to Xbox.com account

Did you try to soft. Rest your xbox yet sometimes that helps alot? Do you knw how to do so?

The account was unable to be signed in.

It would not connect to XBOX live.

When trying to change games would not let log in via microsoft account.

Son has XBOX gold pass etc and no issues prior to this.

I will contact them directly as advised thank you .

If you are unable to solve the issue, you will want to contact xbox support
