Advanced Session lobby findable but can't join

[felix5766751 (aL†aiR)]

Hello guys, I’m currently trying to implement a multiplayer functionality with the Advanced Sessions plugin on UE5.0.2. A player can create a game, which can be found and joined through a server list by another player.

The problem is that, while games can be found, I can’t join it for some reason. I’m running the game on two different machines with different Steam accounts, the DevAppId 480 in the GameEngine.ini and testing in Standalone mode.

Blueprint for creating a lobby:

Blueprint for searching lobbies:

Blueprint to Join lobby:

Server list with game running on other machine:

These are the logs after pressing the Join button from Advanced Session:

Update: It seems like that Multiplayer over Steam doesn’t work when packaging to Shipping, but does work when packaging to Development. I’ve read somewhere that Shipping only works if you get your own SteamID, but I haven’t confirmed it myself yet. Doesn’t explain why it doesn’t work in Standalone, but at least something is working.

Im having the same issue, packaged for development.

in my case the issue was that the map was not cooked properly so i had to add it to the list of maps to cook.

there are multiple ways to do so

List of Maps to cook

DefaultGame.ini [/Script/UnrealEd.ProjectPackagingSettings] bCookAll: if true, cook everything in the content directory. This means that if you have an asset that is not referenced by any others, it will still end up in the cook. From this it follows that the list of maps to be cooked is simply all of them, even if they are not in any other .inis. bCookMapsOnly: this setting only has any effect if bCookAll is set. If it is true, “cook all” does not actually cook every asset, just all maps and…

I had this issue. In server default map I was using the main menu map. you need to set it to main game map.
