PS4 game crashes at GetAllNetworkInterfaces() function

[ibaanb]

Hi,

I'm currently making a multi-player game for PS4 that supports 2-8 players via LAN and WAN. However, when joining a host that does not support UPnP the game would crash and exit game. I discovered that it crashed at GetAllNetworkInterfaces() function in TNTools.cs. I cannot see any debug information, so I'm not sure what the error is caused from. This error specifically occurs when the client(PS4 Devkit) is using a different ISP to join a game, but the Host is using an ISP that does not support UPnP.

Thanks,

Have you tried simply creating a completely empty project with a MonoBehaviour that just does NetworkInterface.GetAllNetworkInterfaces() inside to see what's returned?

I tried to create empty unity project and put the plugin .Net socket that I got from Unity. The error is same when I call GetAllNetworkInterfaces function. I tried to test the other function like GetIsNetworkAvailable function and it is fine.

I suggest you use that empty project and submit a bug to Unity so they fix it.
