Unable to connect server

Recently, I always encounter connectivity issue when accessing UT mode. It shows me "You have lost your online connection. Check your home network. You will not be able to access FC's online features until you can reconnect to EA Serves. Go to ea.com/unable-to-connect to find out more."
I try to reboot router and restart the game and PS5 but still get the error message. I check the connection in my PS5, it is alol good.  Also, it does not have any problem when playing other PS5 games. Please fix my problem ASAP.
