Persistent Disconnection Issues in FC 26 on PS5 - PSN and EA Server Errors

Hi everyone,

I am experiencing a persistent connection issue while playing FC 26 on PS5. I am either unable to connect to the EA servers at all, or I get disconnected within 2-3 minutes after successfully logging in. The error message states that I must be signed in to PSN and EA Servers to access online features.

My Setup and What I have Tried So Far: 

Connection Type: Wired LAN Cable. My home network is stable and other devices work perfectly. 
PSN Status: PlayStation Network is fine and I am signed in. 
DNS Settings: I am using Cloudflare DNS 1.1.1.1 and 1.0.0.1.

Troubleshooting Performed:

• Restarted the console and power-cycled the modem.
• Checked EA account security settings and ensured Login Verification is active.
• Ensured the FC 26 Companion App is completely closed during console sessions.
• Restored Licenses on PS5. 

Despite having a high-speed wired connection and optimized DNS, the game keeps kicking me out of Ultimate Team and other online modes shortly after entry. Is there a specific server-side synchronization issue or a known conflict with Turk Telekom ISP configurations for FC 26? Any guidance would be appreciated. 

Platform: PS5
Region: Turkey
ISP: Turk Telekom

Thank you!
