Internal Server Error

Hello,
My brother is trying to sign into Halo Waypoint using his Microsoft Account, and every time we try to sign in we get a white screen with black text that says “Internal Server Error”. He can’t sign in and I want to give him some extra 2XP codes I got for him. I have to restart the browser & clear the cache to be able to log back in as myself. Does anyone know why this could be? I tried using the support button but nothing happened when I clicked, it just showed me recent General Discussion posts.

Try a different browser.
