Session disconnect after matchmaking: UNetConnection timeout and ValkyrieBeacon failure

Summary

My UEFN project “sapporo_test00” experiences a session disconnect due to a network timeout after uploading and launching a private version. The session connects successfully, but disconnects during EndGame execution.

Steps to Reproduce

  1. Upload the UEFN project “sapporo_test00” as a private version.
  2. Launch Fortnite and start a session using the uploaded island.
  3. Play for 30 seconds and execute EndGame.
  4. Observe that the session disconnects with a timeout error.

Expected Result

The session should remain active after EndGame execution, allowing the player to return to the lobby or restart without disconnection.

Observed Result

The session disconnects with the following log error:
UNetConnection::Tick: Connection TIMED OUT. Closing connection.. Elapsed: 30.01, Threshold: 30.00
BroadcastNetworkFailure: FailureType = ConnectionTimeout
PC: NULL, Owner: ValkyrieBeaconClient_1
AValkyrieBeaconClient::OnFailure - We have registered a failure in the Valkyrie beacon.

Project structure is stable:

  • Verse code not used
  • HUD and reward actors removed
  • Memory usage at 86%, size calculation successful
  • Log confirms: Project sapporo_test00 up to date

The issue appears to be caused by server response delay, not asset overload.
