I can't sign in on xbox.com specifically

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

If you still cannot log into your account, you will need to remove and re-add it to the console.
Step 1: Remove your console account
Press the Xbox  button to open the dashboard.
Click Profile & System > Settings > Account > Remove Accounts.
Select the account you want to remove and confirm the removal.
Note You may need to repeat the account removal process up to five times to delete the account from the list.
Step 2: Restart your Xbox One console
Press and hold the Xbox  button on the center of your Xbox One controller to open Power Center.
Click Restart Console.
Click Restart.
Step 3: Add your account back to the console
Press the Xbox  button to open the dashboard.
Scroll up and select Profile & System > Add or Toggle > Add New.
Enter your Microsoft account email address and password.
Follow the instructions on the screens that follow to finish customizing your settings.

Hope I helped and see you soon

Hi, literallyOmlet I hope you're doing well!

I would recommend trying to delete the browser data you can do this by opening your browser and pressing ctrl+shift+delete and clear all, this happened to me a few weeks ago, and clearing the cache browsing data allowed me to sign into the website.

Hope this helps, and please don't hesitate to reply below if you require more assistance

Many Thanks,

Brandon

Looks like this magically fixed itself after 3 days just now, that's a really weird bug. Thanks a bunch for the help ^^

Yeah I have already tried with different devices and browsers so this seems unrelated btw. I also sent feedback to microsoft in case this is a bug but I don't know how long does that take to get a reply

Hi, literallyOmlet

Did you try deleting the browser data? and if so did it work?

Hope this helps, and don't hesitate to reply below if you require more assistance

Many Thanks,

Brandon
