Xbox Series X - Problem logging into the game

Hello,

Xbox Series X / GPON - Fiber 8 Gb/s

For several minutes now, I haven't been able to log in to the game.

- Sometimes it's stuck on Authentication,
- Sometimes the Login Error screen appears,
- When I try to select a character, it's stuck on connecting to the server, and I get the message: "Abnormal Disconnection - Error: Failed to join any instances."

Greetings
