Keeps disconnecting from EA server

Keeps disconnecting from EA server no matter using wired or wireless connection…
It only happens when playing FC26, but not other online game.. It’s really annoying as all the games will be counted as a loss.
Tried to ping EA.com in my phone which is connected to the same network while playing FC26, no packet loss is observed when my PS5 disconnected from EA servers. I wonder what can be done to improve this issue..
