Hey there,

I am working on a Blueprint based multiplayer game which will run on Steam. I am using the Advanced Sessions plugin to host and find games yet I have a problem with hosting games. Unfortunately, it always fails.

Here are some things:

Output when the game tries to create a session:

LogPlayLevel: [2018.03.01-18.32.40:723][144]LogOnline: Warning: Async task 'FOnlineAsyncTaskSteamCreateLobby bWasSuccessful: 0 LobbyId: 0 LobbyType: 2 Result: '15' k_EResultAccessDenied (access denied)' failed in 0.302356 seconds

Blueprint where the game is created:

DefaultEngine.ini looks like this:

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

[OnlineSubsystem]
DefaultPlatformService=Steam

[OnlineSubsystemSteam]
bEnabled=true
SteamDevAppId=708670
SteamAppId=708670

[/Script/OnlineSubsystemSteam.SteamNetDriver]
NetConnectionClassName="OnlineSubsystemSteam.SteamNetConnection"

I don’t really know what’s wrong with it at this point, so any suggestion will be appreciated.

Thanks in advance.

I am also having this problem, did you find any solutions?

Edit* I actually fixed my issue… I found out I was getting a null player character pass, needed to verify which pc was default for the level.

Make sure you check is Dedicated Server

How are you testing it? Make sure steam is currently running on the computer and you launch a standalone version of the game either through the editor → Play -▼ “Standalone Game” or right-clicking the project in your system explorer and selecting “Launch Game”.

what if you don’t wanna use a dedicated server

I Fixed this issue by checking “Lobbies” to true.
