My Fortnite says unable to sign into your account for Xbox network

Everything matches email wise. When we try and log into fortnite it says unable to sign into your account for xbox live

I have tried that already and everytime rockstar says unable to authenticate with xbox live network. Make sure your account is a live account. My account is a live account.

Hello,

I do not have an X account so I am unable to see whether this issue has been resolved, my son's Fortnite account says this error, however, I can log in to their Fortnite account on my Xbox. Has there been any updates on a possible fix or when the issue will be resolved?

I logged into my xbox and I'm back to no skins on fortnite..where did my data go?

make sure you are signed in on your epic games account that had all of your skins, if you are unable to do so I'd contact https://www.epicgames.com/help/en-US/

whats more, i can't even sign into a profile. i will test my network, it will connect to xbox live, then i will try and sign into my Live profile and it will say "unable to connect to xbox live"
