Hello,

I am trying to set up Steam multiplayer using EOS in unreal 5.7 and I am running into a few issues.

First, in most EOS tutorials that i’ve seen the user must first login using a specific login node and that node does not appear to show up in the blueprint editor. There is only “Show External Login UI” and that doesn’t seem to be what I need.

I also get this error at the begining of the log:  
LogEOSSDK: Error: LogEOSIntegratedPlatform: Integrated Platform Steam cannot be initialized without ManagedBy flags. Flags: 0.LogEOSSDK: Error: LogEOSIntegratedPlatform: Integrated Platform Steam failed to get runtime library path.LogEOSSDK: Error: LogEOS: IntegratedPlatform (STEAM) provider failed to initialize. EOS\_EResult: (EOS\_InvalidParameters)

And when I try to create a session I get the following error:  
LogScript: Warning: Script Msg: CreateSession - Cannot map local player to unique net ID

I have setup the project in the developer portal, enabled all of the required EOS plugins and added the required lines in DefaultEngine.ini

Any help would me much appreciated.
