Issues signing into my Xbox profile after enabling 2FA on my Microsoft account

I've disabled F2A, tried everything I've read in the forums, and still can't re-download my profile on my XBOX 360. it starts go download bug then shows this error code. 8015190A

Some apps and the Xbox 360 don't work with 2FA. Which xbox are you signing into?

sorry, I need to be more specific, the problem isn't the internet the problem is that every time i insert the code that Microsoft sent me, the Xbox says its incorrect.

Hello there @MemeMaster_12, I hope everything is going well!

Thank you for reaching Microsoft Xbox Forum support. I want you not to worry about the situation because I am here to help you out! I believe your console might need either a network reset or just a system refresh. I would like you to go through the following steps to clear the Mac address and then perform a quick power cycle on your console:

Settings > Network Settings > Advanced Settings > Alternate Mac Address > Clear it and the console should restart. It would definitely help if you could restart the internet router while the console is restarting.

After going through the troubleshooting steps mentioned, I invite you to perform a quick power cycle by turning off the console and then unplugging all the cables. After 2 to 3 minutes, re-plug them back again, then restart your console.

Another thing you should check is your NAT type. I would like you to check your NAT type if open because that could sometimes interfere. to check for the NAT type you can follow the steps below:

Settings > Network Settings > NAT type => It should be open.

If the NAT type is not open, you will need to open some ports with your internet provider. These ports must be open for Xbox Live to work: Port 88 (UDP) Port 3074 (UDP and TCP) Port 53 (UDP and TCP) Port 80 (TCP) Port 500 (UDP) Port 3544 (UDP) Port 4500 (UDP).

In case the issue still persists after the previous steps have been performed here is the official link to all the network troubleshooting steps that can help sort this out for you.

In case the issue still persists, the next step would be to perform a reset on the console. To do so you will need to follow the steps below to perform a reset on the Xbox :

Settings > System > Console Info > Reset This Xbox > Reset and Keep my Games and Apps.

Note =>The "Reset and Keep my Games and Apps" option will not cause losing your games, but please be aware that you need to be completely aware of the email address as well as the password of your account before going for it because it will require you to sign in to the account.

I wish you a lovely day, and I hope this helps you out! All the best!

Kind Regards

Stay safe, and happy gaming!

Hello bobbygilmour! I'm Claus, an Independent Microsoft Community Consultant for Xbox! Glad to be able to help you!

Just to make sure we are on the same page, you have enabled the 2-factor authentication on your Xbox Live profile (Microsoft Account) or on your Twitch account? If you have enabled it on the Microsoft Account, you can easily disable it on this page: https://account.microsoft.com/security

This will allow you to sign in to your Twitch account, and should also allow your accounts to connect to one another. After that, try to enable 2FA again on your Microsoft Account.

But on the other hand, if you are having problems on your Twitch account with 2FA, then I recommend you to contact the Twitch Support directly for help with managing your account's security settings.
