Howdy, I’m attempting to debug a server crash of my dedicated server binary…it seems to only fail in my PlayFab server container (restricted windows env), I looks like maybe a DLL error but not sure…I can see all the DLLs referenced in my package that is being deployed, and ListDlls says they should all be accessible I believe…OTOH, I’m wondering if the mistake is more basic…We’re using FMOD for sound events, and I wonder, do I need to guard triggering sound events to be remote only w/ a has authority switch in a dedicated server env?

EDIT: For additional context, this binary on PlayFab runs in a paired down “Windows Server Core” OS.

Additional Log context (on startup):

I can see the DLLs in my server package though 😕

I figured it out, its staring me right in the face. MSACM32.dll isn’t available on Window Server Core, so I need to provide this as part of my deployment, that fixed it. Hope this helps someone else!
