Unable to Connect to EA FC 26 Online Features Despite Stable 400 Mbps Internet

I'm writing to let you know that my EA Sports FC 26 connection is still having problems. I am unable to log in or use any online capabilities even though I have a reliable and fast internet connection (UniFi 400 Mbps). The warning "You have lost your online connection" appears on the screen frequently. Examine the network at home. Until you are able to reconnect to EA servers, you will not be able to use FC's online capabilities.I have verified that other online apps and games are operating regularly, my internet is reliable (as shown by Speedtest), and my console is correctly connected via LAN connection. I've reset my router and console as well, but the problem still exists.
Given that I have been a devoted player of EA Sports football games for over nine years, I am really saddened by this issue. Although I have always loved the game, my entire experience and pleasure have been impacted by this ongoing connection problem.
Please help me find a quick solution to this. If you could investigate if the issue is with EA servers, account status, or my IP settings, that would be greatly appreciated.
