STEAM - Connection Failed Error 1:86001S:66003S:468882297O:0B - EA Backend Issue

I cannot connect to Battlefield 6 servers via Steam. Getting consistent error:

Connection Failed - Error Code: 1:86001S:66003S:468882297O:0B

Platform: Steam (purchased on Steam)

EA Account: Verified linked to Steam at ea.com/account/connections

Troubleshooting Steps Already Completed:

  • Verified game files integrity on Steam (100% validated)
  • Cleared EA App cache via Help > App Recovery
  • Ran EAAntiCheat.GameServiceLauncher.exe as administrator
  • Changed DNS to Google DNS (8.8.8.8 / 8.8.4.4)
  • Restarted router (full power cycle)
  • Logged out and back into EA Account
  • Reinstalled EA App completely
  • Verified Secure Boot and TPM 2.0 enabled

Result: Error persists after all standard fixes.

Additional Information:

Based on forum research, this appears to be an EA backend authentication issue affecting multiple Steam players. The error structure 1:86001S:66003S suggests account ID mismatch that cannot be resolved client-side.

Multiple threads confirm this same error:

  • , ,

Request: This requires EA backend team intervention. Can a community manager or EA staff member escalate this to the authentication team? This is blocking gameplay entirely since launch.
