Cannot connect to Ultimate Team in FC 26 [PC]

Hi there,

since two days I cannot connect to Ultimate Team through the EA App on PC. I always get the message "unable to connect" after some time of trying to connect.
I already tried a couple of things but did not succeed. Can you please guide me on what to do? It is really frustrating if you cannot play a game you bought in the little spare time you have....

Here is what I have done:

• check internet connection (very fast, very stable via LAN)
• flush dns
• change networks
• reinstall EA app
• repair FC 26 game in EA app
• temporarily switch to automatic DNS (from manual which is default)

I can open the game but not enter Ultimate Team...it is so frustrating.

Thank you for helping in advance!
Kai
