can't log into xbox app through phone

I had deleted the app off my phone a year again and reinstalled it recently, but before it worked just fine. When I go to log into the Xbox app on my iPhone xr it says "There is a problem with your Microsoft account, to fix this sign into account.live.com
from a browser." So I went onto my PC and logged in but nothing seemed wrong. I proceeded to log into the Xbox website and got in with no errors. I even downloaded the Xbox app through the Microsoft store on my laptop and also got in without errors. However
when I try to log in on the app on my phone it still says I cant get in. I don't know why this is happening since it worked a year or so ago before i deleted it.
