Why GetNetDriver() after ServerTravel return NULL?

I am monitoring the netdriver because I can’t connect the client to a server.
The Server is open with ServerTravel and the url contains the listen param.
I seen World->GetNetDriver() always return NULL I tried every setting inside the editor and the cooked version, but the only one who return the netdriver is inside the editor, creating the listen server and at least a client.
Can someone enlighten me?

The DefaultEditor.ini contains

[/Script/Engine.GameEngine]
!NetDriverDefinitions=ClearArray
+NetDriverDefinitions=(DefName="GameNetDriver",DriverClassName="OnlineSubsystemUtils.IpNetDriver",DriverClassNameFallback="OnlineSubsystemUtils.IpNetDriver")
+NetDriverDefinitions=(DefName="BeaconNetDriver",DriverClassName="OnlineSubsystemUtils.IpNetDriver",DriverClassNameFallback="OnlineSubsystemUtils.IpNetDriver")

[OnlineSubsystem]
DefaultPlatformService=Null
PollingIntervalInMs=20

[/Script/OnlineSubsystemUtils.OnlineBeaconHost]
ListenPort=7787
BeaconConnectionInitialTimeout=10.0
BeaconConnectionTimeout=10.0
