Question Exception: Could not bind socket when using Unity Transport package in Editor Windows

When I run the new NetCode multiplayer project, I got this error

Code (CSharp):

1. Exception: Could not bind socket
2. Unity.Networking.Transport.BaselibNetworkInterface.Initialize (Unity.Networking.Transport.INetworkParameter[] param) (at Library/PackageCache/com.unity.transport@0.4.1-preview.1/Runtime/BaselibNetworkInterface.cs:197)
3. Unity.Networking.Transport.NetworkDriver..ctor (Unity.Networking.Transport.INetworkInterface netIf, Unity.Networking.Transport.INetworkParameter[] param) (at Library/PackageCache/com.unity.transport@0.4.1-preview.1/Runtime/NetworkDriver.cs:480)
4. Unity.Networking.Transport.NetworkDriver.Create (Unity.Networking.Transport.INetworkParameter[] param) (at Library/PackageCache/com.unity.transport@0.4.1-preview.1/Runtime/NetworkDriver.cs:454)

When I debuged the BaselibNetworkInterface.Bind method, I found the Error.code is UnexpectedError, nativeErrorCode is 10045, nativeCodeType is PlatformDefined.

Unity version: 2020.1.14f1c1 Personal
Platform: Windows 10

It's ok when playing on another computer. I think it's the problem of this PC, but don't know how to fix it. That really drive me mad. Will someone help me?

 

Probably a permissions issue. Try running it as Administrator and see if that resolves the problem.

 

Thanks for your reply. I've tried that, still didn't work. By the way I can run DOTSSample on the same machine which use older version of unity.transport and netcode.

 

Maybe that computer has something running on whatever port the project is connecting on. There should be a way to check what ports are in use and which process has the socket, depending on your OS.

 

Have you got this issue resolved?
I am facing the same issue here , please let me know if you have any progress, any help will be appreciated
