Fc companion login unavailable

Guys can someone please help me Im panicking😔

so from 2-3 weeks ago my companion app wasnt working it was giving the “login unavailable” pop up but later I played fc 26 on the full version then the companion app started working perfectly fine. Fast forward today app was working smoothly no problems then before 15 mins i was playing fc26 on the showcase and when I turned it off properly and went to the companion app that pop up came again and I deleted the app and reinstalled but it didn’t work. Although I was playing in the showcase version from 3 days ago also and was opening the companion app and doing sbcs without any problems but now it came.

please someone find me how to fix the problem Im desperate 😓
