Connection to EA servers on my PS5

I have purchased FC27 a week ago. However, I could not play ultimate team! It says that I have lost my online connection to EA servers and to check my home connection. All mobile devices and other games were working except fc27. I have done all guides provided by EA to solve the connection problem but still could not work. EA please fix this it has been days already... 

Console: PS5 

Region: Hong Kong
