I’ve setup my project, currently to use the Online Session subsystem NULL; just testing local online sessions until the project is further in development. This was working on UE 5.1 and since I’ve moved up to 5.2 now when attempting to join the session it times out. I’ve tried launching game instances outside of the editor (so not in PIE) and packaging a build to put on a second PC and whenever I attempt to join the joining session stalls out for a bit then resets. In the logs I’m seeing that the connection timed out but I’m not seeing any errors as to why. I’ve checked my firewall settings for the .exe and they are set to allow traffic for my network. Has anyone else run into this? Or can anyone see an error I might be missing? Here are the relevant lines from the log (the logtemp are print statements I’ve added to understand when things were happening): 1057 [2023.06.20-22.21.26:940][19]LogTemp: Warning: GR\_GameSession\_0.HandleFindSessionsComplete broadcasted SessionOwnerStrings 1058 [2023.06.20-22.21.28:335][518]LogTemp: Warning: GR\_GameSession\_0.HandleJoinSessionComplete joined attempt SUCCESS, telling controller to travel 1059 [2023.06.20-22.21.28:335][518]LogNet: Browse: 192.168.7.234:0/Game/Developers/SMart/World\_Levels/L\_InitialMap 1061 [2023.06.20-22.21.28:335][518]LogNet: Created socket for bind address: 0.0.0.0:0 1062 [2023.06.20-22.21.28:335][518]LogNet: IpConnection\_0 setting maximum channels to: 32767 1065 [2023.06.20-22.21.28:347][518]LogNet: Game client on port 0, rate 100000 1066 [2023.06.20-22.21.28:347][518]LogNetVersion: RTS\_Prototype\_1 1.0.0.0, NetCL: 25360045, EngineNetworkVersion: 32, GameNetworkVersion: 0 (Checksum: 590619967) 1067 [2023.06.20-22.21.38:336][99]LogNet: Initial Connect Diagnostics: Sent ‘9’ packets in last ‘10.001560’ seconds, no packets received yet. 1068 [2023.06.20-22.21.48:338][687]LogNet: Initial Connect Diagnostics: Sent ‘10’ packets in last ‘10.002297’ seconds, no packets received yet. 1069 [2023.06.20-22.21.48:350][691]LogNet: Warning: UNetConnection::Tick: Connection TIMED OUT.

I just loaded up a build from 5.1 and it is doing the same thing, I’m curious if there may have be a .NET update or some other Windows update that might be causing this to occur. ☹ ---

OnlineSubsystem is being deprecated… Use Online Services instead > ### Online Services > > The Online Services plugins have not been tested in shipping titles. As of UE 5.1, the Online Services plugins are an API-complete version for developers to use with the intention that they will be shipping on a future version of the engine. We also recommend using Online Services for developers targeting their own backend, or those who will be incorporating a number of UE upgrades beyond 5.1 into their project before shipping. > > ### Online Subsystem > > Use the [Online Subsystem](https://docs.unrealengine.com/5.1/en-US/online-subsystem-in-unreal-engine) for any title shipping in the near future, or when you do not plan to incorporate any engine upgrades beyond UE 5.1 into the project. > **[Online Services Overview](https://docs.unrealengine.com/5.1/en-US/overview-of-online-services-in-unreal-engine/)** > > Learn about the Online Services Interfaces and how to configure them for use in Unreal Engine. ---

Not sure this explains why the 5.1 build I have isn’t working but I plan on staying in 5.2 so something I’ll have to look into and change. Thanks! ---

Thanks! Don’t worry about Online Subsystem it still working in UE5.5… and also “Online Services” is garbage
