Constant EA FC Online Disconnects – NOT an ISP Issue

I’m facing constant mid-match disconnections in EA SPORTS FC online modes (Seasons/UT/CO-OP/Friendlies), very often at half-time and sometimes randomly. Error says I’m disconnected from EA servers, but my internet remains fully active.

Platform: PS5
This has happened across multiple titles (EA FC 24 and EA FC 26). 

Before posting here, I have exhaustively ruled out local/network issues. I have tested wired Ethernet and Wi-Fi with the same result, multiple DNS providers including ISP default, Google, Cloudflare, Quad9 and OpenDNS, NAT Type always shows Type 2, UPnP enabled, DMZ configured, and a stable connection with no issues in other online games such as COD and GTA. I have also optimized router settings specifically for EA FC requirements.

This issue is exclusive to EA FC and persists despite everything above, so it cannot reasonably be blamed on my ISP or home network. The disconnects frequently happen during match state changes, especially at half-time, which suggests a session-handling problem.

Is anyone else experiencing the same pattern? If so, please reply so we can establish whether this is a wider EA FC server issue.
