steam sessions

Hi,

I am using a plain 4.8.3. build with a lot of ideas taken from shootergame.
I am trying to get the steam subsystem working, but its not working somehow… If i use the null online system i can perfectly join local games and lan games… I do see the steam overlay on both environments and i am logged in with two separate accounts. I noticed that in the shooter game connections are not that smooth either, but they do work. I activated all logging LogOnlineGame=VeryVerbose and LogOnline=VeryVerbose. Both return no errors and the sessions are created correctly. What could be wrong here? Any other posts about this seem to remain unanswered.

My steps so far:

  • Use steps provided in Online Subsystem Steam Interface in Unreal Engine | Unreal Engine 5.2 Documentation and also had a look at A new, community-hosted Unreal Engine Wiki - Announcements - Epic Developer Community Forums.

  • Added latest version of steam sdk v1.32 dll’s for both windows 64/32 bit.
