Client can't find host, when he has 2 Ethernet Adapters

We have PC with two Ethernet Adapters:

  1. Standard Lan Adapter embedded into the motherboard
  2. VirtualBox Host-Only Ethernet Adapter
    If both adapters are turned on, we have problems with “find session”, because “find session” occurs via second adapter.
    If we turn off second adapter, a “find session” works fine.

Any ideas how to fix this?

Hello ,

I’ve tried reproducing this problem with a USB Ethernet adapter but haven’t had the same results as you’re mentioning. Could you try testing this same issue with the Shootout Game project from the Learn tab on the Epic Games Launcher? When I had both ethernet ports connected, I ended up seeing double the amount of open games whenever another computer on the network was running it. Please be aware that I was using a packaged version of Shootout Game for Windows 64-bit and Development configuration.

We tested “Shootout Game” and all worked fine. So we will try to seek a solution in “Shootour Game” source.

Thanks for your time.

I was getting same case/error and I tried the “ShootOut” project in my case but it is still same. It can not find any session when there is virtual adapter.
