Unable to stay signed into EA servers

Every night for the past week, I keep getting disconnected from the online EA servers despite being signed into my Playstation Network and having 0 internet connectivity issues. I get signed out 15 minutes after starting up the game on Ultimate Team and while doing the simplest of things like an SBC, opening packs, or just simply making changes to my formation/starting 11 before I end up getting disconnected from online servers. Whenever I get signed out, I try reconnecting to the online servers by pressing the “R3” button, just to get a message stating that it is unable to connect and to check that I am signed into my PSN and to check my internet. I am then forced to close the game, do an internet connection test to verify THAT MY INTERNET IS WORKING. My download speeds typically show around 400-470 Mbps, and upload speeds show as 50-70 Mbps, so I clearly do not have any connectivity issues. Once I relaunch the game, I am then met with the same message of being unable to connect to the EA servers and to check that I am signed into PSN and to check my internet connection. After closing and re opening the game again, I am able to connect back and play for anywhere between 15 minutes to 45 minutes before I get greeted with the same message that I have lost my online connection. Sometimes I have to relaunch the game several times before I am able to connect to the servers and stay connected for a few minutes This becomes increasingly frustrating whenever I am playing a squad battle match as I will “lose connection” and be forced to lose a match despite me being ahead in goals against the AI teams. EA, please fix you server connection issues. There is no reason that I should continuously get the same message over and over again despite STAYING SIGNED IN to my PSN account and my home network connection having no interruptions.
