I can't connect my account to discord

Enter the "Discord Connections" options and unlink the Xbox account..

Where do I find options in discord connections?

My name is Fernando I'm an independent consultant, I'm happy to help.

Try the procedure again: To connect to Discord through your Xbox console:
Press the Xbox  button on your controller to open the dashboard.
Go to Profile & System > Settings > Account > Linked Social Accounts.
In the Discord tile, select Link.
Follow the instructions to link your Discord account. If it doesn't work make sure the correct permissions are enabled in Discord to allow the Xbox connection. Make sure you have given Xbox permission to connect to Discord in the Discord app settings. Also make sure that the option "Show status game activities" is turned on.

I hope I helped and see you soon.

When I connected my xbox account to discord I did it on my phone but maybe this link will help you.

I'm assuming this is how you did it, but if it doesn't work try the discord app on your phone.

Hope this helps,

Hi RHENUSEN. My name is Kyle and I'm an independent advisor.

I’m sorry to hear you’re experiencing this issue, are other accounts/services able to link just fine?

I advise contacting Discord Support as the account connection is made on their side: https://support.discord.com/hc/requests/new

Thanks,
Kyle

Hi, my name is Marvina and I will be happy to help you.

I'm sorry you have this problem. Follow the instructions below for a solution.

Aspects that you should take into account:
You cannot mix Discord friends with Xbox friends. A Discord voice channel will contain your Discord friends, while an Xbox group chat will contain your Xbox friends.

Discord voice channel audio cannot be transmitted via Twitch streaming.
Discord is not available in all countries or regions.
Initial tasks

To add Discord to your Xbox, you'll first need to link your Xbox and Discord accounts in one of the following ways.
Note You will only be asked to link the first time, unless you unlink your Discord and Xbox accounts. If you previously linked your Xbox and Discord accounts before August 2022, you may need to link your accounts again to access this feature.

For more information on linking to social media accounts, go to:

Link your social media accounts to Xbox
Select your avatar > Connections.
Select Add and under Add new connection, select Xbox.
Select Continue, then follow the instructions to sign in to your Microsoft account.
Select Authorize to connect your Xbox and Discord accounts. When you're done, your accounts will be linked.
