steam sessions timeout 60s

Hi! I’m running steam sessions on two machines to quickly debug something

I’m using command line to run the project C:\UE_4.27\Engine\Binaries\Win64\UE4Editor.exe “D:\Unreal Projects\mygame5\MyGame.uproject” -game -log
but it seems that level loading takes too much time and the conenction times out on server side after 60 seconds:

[2023.07.07-07.43.21:172][ 51]LogNet: Error: UEngine::BroadcastNetworkFailure: FailureType = ConnectionTimeout, ErrorString = UNetConnection::Tick: Connection TIMED OUT. Closing connection… Elapsed: 60.00, Real: 60.00, Good: 60.00, DriverTime: 1757.90, Threshold: 60.00, [UNetConnection] RemoteAddr: , Name: SteamNetConnection_6, Driver: GameNetDriver SteamNetDriver_0, IsServer: YES, PC: NULL, Owner: NULL, UniqueId: STEAM:, Driver = GameNetDriver SteamNetDriver_0
This happens most of the times, sometimes it doesn’t timeout though
Any way to solve this issue?
(when i build the project the loading time is less and the problem does not exist, but it only prevents me from doing quick troubleshooting)
also this wasn’t the case in 4.26, only in 4.27
