I cant log into a Microsoft account when I put in the code

I have a Nintendo switch. I also have friends on Xbox. I want to play with them but I can't log in to a Microsoft account. I go to aka.ms/remoteconnect and type in the code, but after I do that, there's an error with the name of Failed to login and the message says We tried to sign you in to your Microsoft account, but something went wrong. And I always hate it.
