when I open Minecraft multiplayer an click on a server that I just added, and all servers I have hypiexel. it says failed to login, authentication servers are down. to make sure it wasn't everyone I had my brother do the same thing on his computer and it worked. I search up on YouTube how to fix it and I did every thing it said to do and it still haven't work. and i just got Minecraft java edition so this is my first time playing java edition.
