How do I fix the Login failed error

Whenever I try to login to Fortnite I press start > select account then it says “Login Failed and Retry” when I press retry it makes me go through the cycle again I tried restarting Fortnite, restarting my xbox, exiting out of Fortnite and joining back, removing my Microsoft account and adding it back, checking the connection, resetting my MAC address, and unplugging my xbox for a few minutes. I can play on my account on my Nintendo and successfully log in.
