Unity error when running dedicated server in VMs - unable to connect

[cmalo11]

When running the v1.0 dedicated server in a VM (tried a clean install of W10 and W11), the log file is spammed constantly with this Unity error which prevents connecting to the server:

This issue does not appear when following the same setup instructions on a baremetal PC. When this error is happening, clients cannot connect, the server is not listed on Steam's server listings, but RCON does work and Steam API does find the server on 27016.

I have successfully run pre v1.0 dedicated servers on my VM infrastructure without any issues.

Info about the VM configs tried: Hypervisor: Proxmox OS: W10 and W11 CPU: 4 cores RAM: 16GB (ballooning off and on) Storage: 128GB

I tried the VirtIO drivers on W10, as well as the defaults, no changes.

I meet same issue. I also running my server on proxmox VMs. When I set "ListOnEOS" to "true", server crashes with the same logs.

There are some more information, says EOS dll not found:

Finally found the resolution.

V Rising dedicated server EOS needs DirectX runtimes and Visual C++ Redistributable runtimes installed. (from reddit: https://www.reddit.com/r/vrising/comments/1cn8lmt/comment/l35righ/?utm_source=share&utm_medium=web3x&utm_name=web3xcss&utm_term=1&utm_content=share_button) DirectX: https://www.microsoft.com/en-us/download/details.aspx?id=8109 Visual C++: https://learn.microsoft.com/en-us/cpp/windows/latest-supported-vc-redist?view=msvc-170

Otherwise we must disable "ListOnEOS".

So I've updated both DirectX and Visual C++ but I am still getting this same error. Is there anything else that could be causing this aside from DirectX and Visual C++ needing to be installed since they are, 150%, beyond a shadow of any reasonable doubt, installed.

I am getting the same exact error message as posted above.
