Unable to Connect & Massive performance issues

Hello,

since 5 Days im haveing massive performance issues. It comes in all kind of forms. Sometimes i cant collect loot, sometimes the server is not responding.
10 Minutes ago i got kicked out of the game, now i cant log in anymore. It says me either "Connecting" or "Authenticatin". After 1 Minute it tells me Conenction failed.

I can tell that the Internetconnection is fine because other people in my house are playing with no problem.
Computer Performance is also fine, almost no CPU Usage (around 10-30%) , Memory and SSD also no Problems.

Is there maybe an issue with the session of my character? Can someone help me?

Pretty sure its the server.
They had power outages the other day. Looks like the same thing is happening now.

Same here stuck at "Connecting"

same here cant connect
