Consistent disconnection from competition modes

I recently purchased FC26 for PS5, there's no issues playing Rush. However whenever I try playing rivals or the gauntlet matches I keep getting disconnected and receiving DNS notifications. It's really frustrating. I've tried changing the router and reinstalling the game but I still keep receiving the error. I can't even seem to submit this issue on the EA Contact hence my last resort is to post a thread here hoping for a permanent solution. I'm from Singapore and have been playing previous versions of FC but this is the first time I'm experiencing these technical issues.
