Linux and Steam Integration Problem

Hi, I have a Linux Server build. My matchmaking algoritm is working well in test project. But I tried with my actual game which uses Steam API, I couldn't join the server. I looked on Unreal's forum and see exact my issue. He/she fixed with adding Steam dll's. But I don't know how to add .dll's into Linux build. Can someone help me? I'm adding Linux Server logs below.

DLL files in Windows are the shared object (.so) files in Linux. Currently, PlayFab only provide ListDLLS( Determining required DLLs for Windows game servers - PlayFab | Microsoft Learn) to check the required DLLs of the program running on Windows.

Your server error log "steamclient.so: cannot open shared object file: No such file or directory\n" shows that the steamclient .so file is not included in your server build, you may find the file and paste it to your server build.

Thanks for answer. I put steamclient.so in server build but it's not working. Because it's looking for "/home/ue/.steam/sdk64/steamclient.so" file, not my server folder. So I need to do link those 2 folders somehow. Since I don't know anything about Linux, it'll be great challenge. :=)

Sorry for the late reply. You can try to find the file path "/LinuxServer/TestGameName/Binaries/Linux" in your server build and paste the 64bit steamclient.so into this path.
