"Servers cannot process your request" error when entering MUT

I haven’t been able to log into Ultimate Team for several days, even though it used to work fine before. I’ve changed my DNS to Google DNS, I’m using a wired connection (modem was rebooted, pc was rebooted, logged in and out of account), the date and time on my PC are correct, and my account status in the EA App shows as online, I also changed EA password. My account isn’t banned or restricted, and my EA Play subscription is active. I' playing on PC. Please check this and help me resolve the issue.
