Hi. We are using Unreal Engine and Legacy Multiplayer fro game. The client launches the game using UPlayFabClientAPI::StartGame (from marketplace PlayFab plugin). After moving from ue4.22 to ue4.24, we cannot connect to the server, or the server cannot started successfully. When the game starts, the client receives a valid response from PlayFab with connecting information (LobbyID, ServerHostname, ServerIPV4Address, ServerPort and other). But the server is shutting down a few seconds after starting. Unable to connect to it. There are no logs in the Archived Games section.
Everything works fine in the local docker container.
We included in the build all the dependencies that tool "ListDlls" showed. The folder for the logs is set via the start parameter "-ABSLOG = <log_file_path>".
Also we tried to launch an empty blueprint ue4.24 project. It started and worked for several minutes until it was turned off manually. An empty ue4.24 project with C ++ code did not start. But PlayFab returned an Internal server error. Also we can't get log file from empty server's build ue4.24, but we know for sure that it runs correctly, since it responds to connection requests.
How can we understand the reason why the server crashes or not started?
Last build version HG_Server_0212_03
